ASoC: soc-pcm: share DPCM BE DAI stop operation
soc-pcm has very similar but different DPCM BE DAI stop operation at
1) dpcm_be_dai_startup() error case rollback
2) dpcm_be_dai_startup_unwind()
3) dpcm_be_dai_shutdown()
The differences are
1) for rollback
2) Doesn't check by snd_soc_dpcm_be_can_update() (Is this bug ?)
3) Do soc_pcm_hw_free() if it was not !OPENed and !HW_FREEed,
and call soc_pcm_close().
We can share same code by
1) hw_free is not needed. Needs last dpcm as rollback.
2) hw_free is not needed.
3) hw_free is needed.
This patch adds new dpcm_be_dai_stop() and share these 3.
