li->dais is same as number of CPU + Codec,
li->conf is same as number of Codec when dummy-Codec.
li->dais/li->conf are no longer needed.
This patch removes these.

We couldn't setup dai_props cpu_dai/codec_dai at the initial timing,
because "counting DAIs loop" and "detecting DAIs loop" were different.
But we can do it now, because these are using same loops.
This patch setups dai_props cpu_dai/codec_dai at the initial timing.
It can removes triky code from simple-card / audio-graph.

Current simple-card / audio-graph creates 1xCPU + 1xCodec + 1xPlatform
for all dai_link, but some of them is not needed.
For example Platform is not needed for DPCM BE case.
Moreover, we can share snd-soc-dummy DAI for CPU-dummy / dummy-Codec
in DPCM.
This patch adds dummy DAI and share it when DPCM case,
I beliave it can contribute to reduce memory.
By this patch, CPU-dummy / dummy-CPU are set at asoc_simple_init_priv(),
thus, its settings are no longer needed at DPCM detecting timing
on simple-card / audio-graph.
Moreover, we can remove triky Platform settings code for DPCM BE,
because un-needed Platform is not created.

The 'single_cpu' local variable is assigned by asoc_simple_parse_dai()
and later used in a asoc_simple_canonicalize_cpu() call, assuming the
entire function did not exit on errors.
However the first function returns 0 if passed device_node is NULL,
thus leaving the variable uninitialized and reporting success.

audio-graph checks DT links 2 times. 1st is for counting DAIs / links
to allocating memory, 2nd is for detecting DAIs.
To detecting DAIs as CPU-dummy -> dummy-Codec order when DPCM case,
it uses loops 2 times.
Because of this kind of complex background, it needs to use local
varuable for it, and each call-back functions need to care about it.
Now, 1st and 2nd DT link check are using same order,
thus we can share same code. This patch do it.

This commit exposes following functions which can be used by a sound
card driver based on generic audio graph driver. Idea is vendors can
have a thin driver and re-use common stuff from audio graph driver.
- graph_card_probe()
- graph_parse_of()
In doing so a new header file is added for above. The graph_probe()
function is simplified by moving more common stuff to graph_parse_of().

Add new members in struct 'asoc_simple_priv'. Idea is to leverage
simple or graph card driver as much as possible and vendor can
maintain a thin driver to control the behavior by populating these
newly exposed members.
Following are the members added in 'asoc_simple_priv':
- 'ops' struct: In some cases SoC vendor drivers may want to
implement 'snd_soc_ops' callbacks differently. In such cases
custom callbacks would be used.
- 'force_dpcm' flag: Right now simple or graph card drivers
detect DAI links as DPCM links if:
* The dpcm_selectable is set AND
* Codec is connected to multiple CPU endpoints or aconvert
property is used for rate/channels.
So there is no way to directly specify usage of DPCM alone. So a
flag is exposed to mark all links as DPCM. Vendor driver can
set this if required.
- 'dpcm_selectable': Currently simple or audio graph drivers
provide a way to enable this for specific compatibles. However
vendor driver may want to define some additional info. Thus
expose this variable where vendor drivers can set this if
required.
Audio graph driver is updated to consider above flags or callbacks.
Subsequent patches in the series illustrate usage for above.

For open platforms, which can support pluggable audio cards, Codec
endpoint is not fixed always. It actually depends on the compatible
HW module that is going to be connected. From SoC side the given I/O
interface is always available. Hence such links have fixed CPU endpoint
but no Codec endpoint. This patch helps to support such links where
user can populate Codec endpoint only and its fields in Platform DT
depending on the plugged HW.

PCM devices are created for FE dai links with 'no-pcm' flag as '0'.
Such DAI links have CPU component which implement either pcm_construct()
or pcm_new() at component or dai level respectively. Based on this,
current patch exposes a helper function to identify such components
and populate 'no_pcm' flag for DPCM DAI link.
This helps to have BE<->BE component links where PCM devices need
not be created for CPU component involved in such links.

For multiple instances of components, using DAI name alone for DAI links
is causing conflicts. Components can define multiple DAIs and hence using
just a device name won't help either. Thus DT device node reference and
DAI names are used to uniquely represent DAI link names.

Add a helper to walk through all the DAIs and set dpcm_playback and
dpcm_capture flags based on the DAIs capabilities, and use this helper
to avoid setting these flags arbitrarily in generic cards.
The commit referenced in the Fixes tag did not introduce the

detecting invalid configurations.

ALSA SoC try to rebind Sound Card if Card/CPU/Codec/Platform
were unbinded and re-binded again.
But, Audio Graph Card might can't rebind again if user do for example
unbind CPU or Codec driver
bind CPU or Codec driver
Because Audio Graph Card is still pointing old/unbinded
CPU or Codec driver's DAI name at dlc->dai_name.
To avoid this issue, it needs to alloc memory and keep DAI name
even though if CPU or Codec driver was unbinded.
Or, always do unbind/bind at Sound Card.
For now, this patch indicates this issue as FIXME.

commit ae3cb5790906b ("ASoC: audio-graph-card: merge
audio-graph-scu-card") merged audio-graph-scu-card which can
handle DPCM into audio-graph-card.
By this patch, the judgement to select "normal sound card" or
"DPCM sound card" is based on its OF-graph endpoint connection.
But, because of it, existing "audio-graph-card" user who is
assuming "normal sound card" might select DPCM unintentionally.
To solve this issue, this patch allows "audio-graph-card" user
can select "normal sound card", and "audio-graph-scu-card" user
can select both "normal sound card" and "DPCM sound card".
This keeps compatibility collectry.

Historically, simple-card/simple-scu-card/audio-graph/audio-graph-scu
are similar but different generic sound card.
simple-scu-card which was for DPCM was merged into simple-card, and
audio-graph-scu which was for DPCM was merged into audio-graph.
simple-card is for non OF graph sound card, and
audio-graph is for OF graph sound card.
And, small detail difference (= function parameter, naming, etc)
between simple-card/audio-graph has been unified.
So today, the difference between simple-card/audio-graph are
just using OF graph style, or not.

audio-graph-card is now supporting normal sound and DPCM sound.
For DPCM sound, original sound card (= audio-graph-scu) had been
supported 1 CPU : 1 Codec connection which uses hw_params_fixup()
for convert-rate/channel.
But, merged audio-graph-card is completely forgeting about it.
This patch re-support it.

for convert-rate/channel.
But, merged audio-graph-card is completely forgeting about it.
To re-support 1 CPU : 1 Codec DPCM for hw_params_fixup(),
it need to judge whether it is DPCM by checking convert-rate/channel.
For this purpose, this patch adds asoc_graph_card_get_conversion()
as preparation

Current audio-graph-card is handling "prefix" by many ways.
But, it is not useful and readable.
We want to do is that allow having it everywere.
This patch supports it.
It will be overwrote if lower node has it.
sound {
prefix = "xxx"; // initial
};
codec {
audio-graph-card,prefix = "xxx"; // overwrite
ports {
prefix = "xxx"; // overwrite
port {
prefix = "xxx"; // overwrite
};
};
};

audio-graph-card and audio-graph-scu-card are very similar driver,
but the former is supporting normal sound card,
the latter is supporting DPCM sound card.
We couldn't use normal sound and DPCM sound in same sound card by
audio-graph-card.
This patch merges both sound card into it.
Now we can use both feature on same driver.
audio-grap-card is now supporting .compatible = "audio-graph-scu-card".

In DPCM case, it uses CPU-dummy / dummy-Codec dai links, and
non DPCM case, it uses CPU-Codec dai links.
Now, we want to merge audio-graph-card and audio-graph-scu-card.
These sound cards are using silimar but not same logic on each functions.
Then, of course we want to share same logic.
To compromise, this patch uses cpu/codec pointer on audio-graph-card.
It is same logic with audio-graph-scu-card, thus easy merging.
This is prepare for merging audio card
