ASoC: soc-core: don't call snd_soc_dapm_new_dai_widgets() at snd_soc_register_dai()
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.
