ASoC: dt-bindings: Move port/ports properties out of audio-graph-port.yaml
Users of the audio-graph-port schema need to define how many ports
and what each port is, so they need to define 'ports' and/or 'port'
anyways. Let's drop 'ports' and 'port' from the schema and adjust users
to reference audio-graph-port.yaml from a port property.
