[PATCH 4/8] ASoC: soc-pcm: add dpcm_fe_dai_clean()

[Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>]

From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

dpcm_fe_dai_close() and error case of dpcm_fe_dai_open()
need to do same cleanup operation.
To avoid duplicate code, this patch adds dpcm_fe_dai_clean()
and use it.
