Current soc-core.c has snd_soc_{of_}get_dai_name() to get DAI name for dlc (snd_soc_dai_link_component). It gets .dai_name, but we need .of_node too. Therefor user need to arrange.
It will be more useful if it gets both .dai_name and .of_node. This patch adds snd_soc_{of_}get_dlc() for it, and convert to use it.
