Merge series "ASoC: soc-pcm: cleanup soc_new_pcm() and bugfix" from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>: 

Hi Mark

These are soc-pcm cleanup patchset.

	1) - 3) : cleanup soc_new_pcm() function
	4)      : cleanup dpcm_runtime_merge_xxx() function
	5)      : bugfix of snd_pcm_limit_hw_rates() order

Kuninori Morimoto (5):
  1) ASoC: soc-pcm: tidyup pcm setting
  2) ASoC: soc-pcm: add soc_get_playback_capture() and simplify soc_new_pcm()
  3) ASoC: soc-pcm: add soc_create_pcm() and simplify soc_new_pcm()
  4) ASoC: soc-pcm: use snd_pcm_hardware at dpcm_runtime_merge_xxx()
  5) ASoC: soc-pcm: fixup snd_pcm_limit_hw_rates() timing
