This series makes mt6358, cros_ec_codec, and mt8183-mt6358-ts3a227-max98357
support WoV (wake on voice).

The first 3 commits are some cleanups and refactors.  It looks like
breaking the existing interface.  But please be noticed that, the
cros_ec_codec has not used by any real device yet.  The refactor is
very necessary to keep the style consistent and for easier to further
extend and maintain.
  platform/chrome: cros_ec: remove unused EC feature
  ASoC: cros_ec_codec: refactor I2S RX
  ASoC: cros_ec_codec: extract DMIC EC command from I2S RX

The 4th commit extends the feature offered from EC codec.
  platform/chrome: cros_ec: add common commands for EC codec

The 5th commit changes the behavior of setting and getting DMIC gains.
  ASoC: cros_ec_codec: read max DMIC gain from EC codec

The 6th and 7th commit make cros_ec_codec support WoV.
  ASoC: dt-bindings: cros_ec_codec: add SHM bindings
  ASoC: cros_ec_codec: support WoV

The 8th commit sets necessary registers on mt6358 to support WoV.
  ASoC: mediatek: mt6358: support WoV

The last 2 commit make machine driver mt8183-mt6358-ts3a227-max98357
support WoV if ec-codec is in DTS.
  ASoC: dt-bindings: mt8183: add ec-codec
  ASoC: mediatek: mt8183: support WoV
