From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

The difference between simple-card / audio-graph are just using
OF graph style, or not. In other words, other things should be same.
This means, simple-card/audio-graph common functions should be
implemented at simple-card-utils, and its own functions should be
implemented at each files.

Current simple-card / audio-graph are using
asoc_simple_card_parse_dai() which is different implementation.
But, these are implemanted at simple-card-utils.
It should be implemanted at each files.
This patch separate these into each files.
