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
ectool cbi set 6 0x00000100 4 2
> AUDIO=MAX98373_ALC5682I_I2S
ectool cbi set 6 0x00000200 4 2
> AUDIO=MAX98373_ALC5682_SNDW
ectool cbi set 6 0x00000300 4 2
