ASoC: soc-component: add snd_soc_component_of_xlate_dai_name()

Browse Source 
Current ALSA SoC is directly using component->driver->xxx,
thus, it is deep nested, and makes code difficult to read,
and is not good for encapsulation.
This patch adds new snd_soc_component_of_xlate_dai_name() and use it
