ASoC: soc-pcm: call snd_soc_dai_startup()/shutdown() once
Current soc_pcm_open() calls snd_soc_dai_startup() under loop.
Thus, it needs to care about started/not-yet-started codec DAI.
But, if soc-dai.c is handling it, soc-pcm.c don't need to care
about it.
This patch adds started flag to soc-dai.h, and simplify soc-pcm.c.
This is one of prepare for cleanup soc-pcm-open()
