In the existing definition of sdw_stream_runtime, the 'type' member is
never set and defaults to PCM. To prepare for the BPT/BRA support, we
need to special-case streams and make use of the 'type'.
No functional change for now, the implicit PCM type is now explicit.

Add get and set channel maps support from codec to cpu dais.
Implemented logic to get the channel map in case of only sdw stream and
set channel map only for specific cpu dais.

Fix few trivial code style issues, pointed out by checkpatch, so they do
not get copied to new code (when old code is used as template):
WARNING: Prefer "GPL" over "GPL v2" - see commit bf7fbeeae6db ("module: Cure the MODULE_LICENSE "GPL" vs. "GPL v2" bogosity")
WARNING: function definition argument 'struct platform_device *' should also have an identifier name
ERROR: code indent should use tabs where possible
WARNING: please, no spaces at the start of a line
WARNING: Missing a blank line after declarations
WARNING: unnecessary whitespace before a quoted newline

Newer Qualcomm SoC soundcards will need to allocate Soundwire stream
runtime in their startup op. The code will be exactly the same for all
soundcards, so add a helper for that.

Move the includes of binding headers from Qualcomm SoC sound drivers
headers to unit files actually using these bindings. This reduces the
amount of work for C preprocessor and makes usage of bindings easier to
follow. No impact expected on the final binaries.

unpreparing/disabling and preparing/reenabling soundwire ports is not required
for every prepare call, this add lots of click and pop noise if we do this in

Older Qualcomm platforms like APQ8016 do not have hardware support for
SoundWire, so kernel configurations made specifically for those platforms
will usually not have CONFIG_SOUNDWIRE enabled.
Unfortunately commit 8d89cf6ff229 ("ASoC: qcom: cleanup and fix
dependency of QCOM_COMMON") breaks those kernel configurations, because
SOUNDWIRE is now a required dependency for SND_SOC_QCOM_COMMON (and in
turn also SND_SOC_APQ8016_SBC). Trying to migrate such a kernel config
silently disables SND_SOC_APQ8016_SBC and breaks audio functionality.
The soundwire helpers in common.c are only used by two of the Qualcomm
audio machine drivers, so building and requiring CONFIG_SOUNDWIRE for
all platforms is unnecessary.
There is no need to stuff all common code into a single module. Fix the
issue by moving the soundwire helpers to a separate SND_SOC_QCOM_SDW
module/option that is selected only by the machine drivers that make
use of them. This also allows reverting the imply/depends changes from
the previous fix because both SM8250 and SC8280XP already depend on
SOUNDWIRE, so the soundwire helpers will be only built if SOUNDWIRE
is really enabled.
