ASoC: simple-card-utils: separate asoc_simple_card_parse_dai()
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. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
