ALSA SoC has 2 functions. snd_soc_register_dai() is used from topology snd_soc_register_dais() is used from snd_soc_add_component()
In general, people think like _dai() is called from _dais() with for loop. But in reality, these are very similar but different implementation. We shouldn't have duplicated and confusing implementation.
snd_soc_register_dai() is now used from topology. But to reduce duplicated code, it should be used from _dais(), too.
Because of topology side specific reason, it is calling snd_soc_dapm_new_dai_widgets(), but it is not needed _dais() side.
This patch factorizes snd_soc_register_dai() to topology / _dais() common part, and topology specific part. And do topology specific part at soc-topology.
