From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com
audio-graph-scu-card.c is supporting "convert-rate/channels" which is used for DPCM. But, sound card might have multi codecs, and each codec might need each convert-rate/channels.
This patch supports each codec's convert-rate/channles support. top node convert-rate/channels will overwrite settings if exist.
It can't support each codec's convert-rate/channels if sound card had multi codecs without this patch.
