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.
