Merge series "ASoC: soc-pcm cleanup step5" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

Hi Mark

These are v2 resend of soc-pcm cleanup step5.
1) - 4) are rebased to latest for-5.7 branch.
5) - 6) are remaked of previous [6/8], [7/8] which were mistaken patch.

Kuninori Morimoto (6):
  1) ASoC: soc-pcm: move dpcm_fe_dai_close()
  2) ASoC: soc-pcm: add dpcm_fe_dai_cleanup()
  3) ASoC: soc-pcm: use snd_soc_dai_get_pcm_stream() at dpcm_set_fe_runtime()
  4) ASoC: soc-pcm: tidyup dulicate handing at dpcm_fe_dai_startup()
  5) ASoC: soc-pcm: check DAI's activity more simply
  6) ASoC: soc-pcm: Do Digital Mute for both CPU/Codec in same timing.
