The PLLs should be set with a VCO frequency in the 900MHz – 1GHz range
to minimize jitter and ppm error for Tegra264. Add the PLLA rate
accordingly.
Therefore, use 983040000 frequency is for multiple of 8K frequencies
and 993484800 frequency is for multiple of 11.025K frequencies.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all drivers below sound/soc to use .remove(), with the eventual
goal to drop struct platform_driver::remove_new(). As .remove() and
.remove_new() have the same prototypes, conversion is done by just
changing the structure member name in the driver initializer.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
simple_util_remove() returned zero unconditionally. Make it return void
instead and convert all users to struct platform_device::remove_new().

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Tegra audio graph card has many DAI links which connects internal
AHUB modules and external audio codecs. Since these are DPCM links,
hw_params() call in the machine driver happens for each connected
BE link and PLLA is updated every time. This is not really needed
for all links as only I/O link DAIs derive respective clocks from
PLLA_OUT0 and thus from PLLA. Hence add checks to limit the clock
updates to DAIs over I/O links.
This found to be fixing a DMIC clock discrepancy which is suspected
to happen because of back to back quick PLLA and PLLA_OUT0 rate
updates. This was observed on Jetson TX2 platform where DMIC clock
ended up with unexpected value.

The SoC sound core will generate a driver name by normalizing the card
name. However, most of the time that name does not tell anything about
the driver and is therefore useless for this purpose.
Make the driver name more useful by setting it explicitly during card
initialization.

Following functions are renamed for a better global visibility.
graph_card_probe() --> audio_graph_card_probe()
graph_parse_of() --> audio_graph_parse_of()
graph_remove() --> audio_graph_remove() [exported as well]
The references of these are updated in audio graph and Tegra audio
graph card drivers.

Add Tegra audio machine driver which is based on generic audio graph card
driver. It re-uses most of the common stuff from audio graph driver and
uses the same DT binding. Required Tegra specific customizations are done
in the driver and additional DT bindings are required for clock handling.
Details on the customizations done:
- Update PLL rates at runtime: Tegra HW supports multiple sample rates
(multiples of 8x and 11.025x) and both of these groups require different
PLL rates. Hence there is a requirement to update this at runtime.
This is achieved by providing a custom 'snd_soc_ops' and in hw_param()
callback PLL rate is updated as per the sample rate.
- Internal structure 'tegra_audio_graph_data' is used to maintain clock
handles of PLL.
- The 'force_dpcm' flag is set to use DPCM for all DAI links.
- The 'component_chaining' flag is set to use DPCM with component model.
