ASoC: amd: renoir: Add check for acp configuration flags
We have SOF and generic ACP support enabled for Renoir platforms
on some machines. Since we have same PCI id used for probing, add
check for machine configuration flag to avoid conflict with newer
pci drivers. Such machine flag has been initialized via dmi match
on few Chrome machines. If no flag is specified probe and register
older platform device.

ASoC: AMD: fix depend/select mistake on SND_AMD_ACP_CONFIG
on i386 or x86_64:

when # CONFIG_ACPI is not set,
so SND_SOC_ACPI is not set:

WARNING: unmet direct dependencies detected for SND_AMD_ACP_CONFIG
  Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] &&
  SND_SOC_ACPI [=n]
  Selected by [y]:
  - SND_SOC_AMD_ACP_COMMON [=y] && SOUND [=y] && !UML && SND [=y] &&
  SND_SOC [=y] && X86 [=y] && PCI [=y]

This problem is due to the unconditional selection of
SND_AMD_ACP_CONFIG in other options. Using 'depends on' solved an
initial problem but exposed another, let's use select instead.

ASoC: amd: Add module to determine ACP configuration
ACP hw block configuration differs across various distributions
and hence it's required to register different drivers module for
distributions. For now we support three ACP drivers:

* ACP without SOF use case
* ACP with SOF use case
* ACP with SOF use case for DMIC and non SOF for I2S endpoints

As all above driver registers with common PCI ID for ACP hw block
we need code to determine ACP configuration and auto select driver
module. This patch expose function that return configuration flag
based on dmi checks for a system. ACP driver module probe register
platform device based on such configuration flag to avoid conflict
with other ACP drivers probed for same PCI ID.

ASoC: fix unmet dependencies on GPIOLIB for SND_SOC_DMIC
When SND_SOC_AMD_RENOIR_MACH or SND_SOC_AMD_RV_RT5682_MACH
are selected, and GPIOLIB is not selected, Kbuild gives
the following warnings, respectively:

WARNING: unmet direct dependencies detected for SND_SOC_DMIC
  Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && GPIOLIB [=n]
  Selected by [y]:
  - SND_SOC_AMD_RENOIR_MACH [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_AMD_RENOIR [=y]

and

WARNING: unmet direct dependencies detected for SND_SOC_MAX98357A
  Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && GPIOLIB [=n]
  Selected by [y]:

This is because SND_SOC_DMIC and SND_SOC_MAX98357A are
selected by SND_SOC_AMD_RV_RT5682_MACH and SND_SOC_AMD_RENOIR_MACH,
respectively. However, neither of the selectors depend on or select GPIOLIB,
despite their selectees depending on GPIOLIB.

These unmet dependency bugs were detected by Kismet,
a static analysis tool for Kconfig. Please advise if this
is not the appropriate solution.

ASoC: amd: Add common framework to support I2S on ACP SOC
We are using legacy way of exposing dais and DMA configuration that
requires separate driver modules for various ACP SOC with almost
similar hw configuration. Moreover the legacy approach requires
separate I2S and DMA module platform devices registration and need
machine specific quirk to control various I2S endpoints. Add generic
dai driver and platform driver for I2S controller on ACP hw block.
This common framework can be used by various ACP platform devices
that shares common specs.

ASoC: rt5682: split i2c driver into separate module
With SND_SOC_AMD_RV_RT5682_MACH using the i2c version of the
driver, we can easily get a build failure when I2C is built-in
but soundwire is not:

 WARNING: unmet direct dependencies detected for SND_SOC_RT5682
   Depends on [m]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && (I2C [=y] || SOUNDWIRE [=m]) && (SOUNDWIRE [=m] || !SOUNDWIRE [=m]) && (I2C [=y] || !I2C [=y])
   Selected by [y]:
   - SND_SOC_AMD_RV_RT5682_MACH [=y] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_SOC_AMD_ACP3x [=y] && I2C [=y] && CROS_EC [=y]

Rework the driver to have three separate modules, with the
main driver just dealing with the common bits and the actual
initialization as part of i2c and sdw specific modules.

The conversion is fairly mechanical to keep it easy to review,
i.e. it moves code around with the minimal required renaming
and changes.
