DT binding properties are available to fixup rate and channel
parameters of a DAI. This series extends this to sample format
conversion as well. With this now DAI PCM parameters (channels,
sample rate and sample format) can be fixed up as necessary in
an audio path.

Changelog:
==========
  v2->v3:
  -------
    * Fix DT binding errors in simple-card.yaml
    * Drop simple-card binding changes from the series since
      there is no usage requirement. It can be extended later
      when necessary.
    * Use definitions instead of properties in the common schema
      and re-use this in audio-graph related bindings.

  v1->v2:
  -------
    * Move DAI params properties to a new schema and re-use this
      for simple-card and audio-graph-card.
    * Use string type for DAI format binding as suggested by
      Krzysztof.
