ASoC: soc-core.c: add snd_soc_dlc_use_cpu_as_platform()

Current snd_soc_is_matching_component() checks "of_node" or "dai_args".
Thus coping "of_node" only is not enough to use CPU as Platform.
This patch adds snd_soc_dlc_use_cpu_as_platform() and help it.

This is helper function for multi Component support.
