ASoC: rsnd: cleanup rsnd_dai_of_node()

Browse Source 
It calls rsnd_dai_of_node() to know it was called from Audio Graph
Card/Card2, or from Simple Audio Card. And after that, it gets
number of related DAIs.

To be more simple code, this patch merges these.
This is prepare for multi Component support.
