ASoC/soundwire: add initial support for SDCA

Merge series from Bard Liao <yung-chuan.liao@linux.intel.com>:

We need to get rt712 version by reading SDCA version and functions.
This patch series adds initial support for SDCA and add a helper to tell
if the codec is RT712_VB.

This series may go via the ASoC tree with Vinod's Acked-by tag.

Bard Liao (1):
  soundwire: sdw_intel: include linux/acpi.h

Pierre-Louis Bossart (10):
  ASoC/soundwire: remove sdw_slave_extended_id
  ASoC: SDCA: add initial module
  soundwire: slave: lookup SDCA version and functions
  ASoC: SDCA: add quirk function for RT712_VB match
  ASoC: rt712-sdca: detect the SMART_MIC function during the probe stage
  ASoC: soc-acpi: introduce new 'machine check' callback
  ASoC: sdw_utils: add SmartMic DAI for RT712 VB
  ASoC: sdw_utils: add SmartMic DAI for RT713 VB
  ASoC: Intel: soc-acpi: add is_device_rt712_vb() helper
  ASoC: SOF: Intel: hda: use machine_check() for SoundWire
