mb/intel/adlrvp: Enable I2S audio codecs on ADL-M RVP 

- Add configurability using FW_CONFIG field in CBI, to
enable/disable I2S codec support for MAX98373 codecs
- AUDIO=ADL_MAX98373_ALC5682I_I2S: enable max98373 codec
using expansion board

Bug=None
Test=With CBI FW_CONFIG set to 0x100, check I2S audio output
on expansion card
