mb/google/volteer: Add firmware configuration probing for audio
For all of the audio devices in devicetree.cb add the probe matches that will determine if the device should be enabled or not based on the selected audio daughter board type.
AUDIO=MAX98357_ALC5682I_I2S: enable max98357 and alc5628, disable others AUDIO=MAX98373_ALC5682I_I2S: enable max98373 and alc5682, disable others AUDIO=MAX98373_ALC5682_SNDW: enable soundwire devices, disable others
BUG=b:147462631 TEST=test different device present in ACPI based on fw_config value:
AUDIO=NONE
ectool cbi set 6 0x00000000 4 2
AUDIO=MAX98357_ALC5682I_I2S
