Add YAML schema for Tegra audio graph sound card DT bindings. It uses the same DT bindings provided by generic audio graph driver. Along with this few standard clock DT bindings are added which are specifically required for Tegra audio.

Where's the graph? You need to define the ports and reference the common schema.
I am looking to reference the bindings used in below doc which is not yet in YAML format. Only additional properties I listed here. {LINUX}/Documentation/devicetree/bindings/sound/audio-graph-card.txt
Should I keep this doc to *.txt format as well and later move to YAML or is there a way to reference *.txt doc here?
The dependency here is like below, Tegra audio graph card -> generic audio graph card (audio-graph-card.txt) -> graph (graph.txt)
I plan to convert dependencies to json-schema in next revision and then refer these for Tegra audio graph card.
