[PATCH 2/4] ASoC: dt-bindings: Use OF graph schema

[Rob Herring]

Now that we have an OF graph schema, let's use it for the
audio-graph-port schema.

There's no need to define 'ports' nodes as specific bindings must define
that and port numbering of the child 'port' nodes.

Note that graph.yaml is part of dtschema now intead of the kernel tree.
