ASoC: dt-bindings: Definitions for DAI params 



The "convert-channels" and "convert-rate" bindings are available for
audio-graph-card and are documented in the audio-graph-port.yaml and
the audio-graph.yaml. There is duplication of property details at
multiple places.

Introduce a new schema to have common definitions for DAI params and
these can be re-used in other schemas wherever applicable. Presently
update audio-graph-card bindings to use these definitions. If required
simple-card bindings can be extended to make use of common definitions.
