ASoC: dt-bindings: audio-graph-port related update

Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

Audio-Graph-Card and Simple-Audio-Card are similar Card
and are sharing same utils. Thus we can also sharing same schema.

This patch-set fixup some Renesas's "make dtbs_check".
