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

Hi Mark

These are not so important, but for
soc-pcm cleanup patches.

Kuninori Morimoto (6):
  ASoC: soc-pcm: move dpcm_set_fe_update_state()
  ASoC: soc-pcm: add dpcm_set_be_update_state()
  ASoC: soc-pcm: add soc_pcm_set_dai_params()
  ASoC: soc-pcm: cleanup soc_pcm_apply_symmetry()
  ASoC: soc-pcm: cleanup soc_pcm_params_symmetry()
  ASoC: soc-pcm: setup pcm at one place in soc_new_pcm()
