Current ALSA SoC is directly using component->driver->xxx, thus, the code nested deeply, and it makes code difficult to read, and is not good for encapsulation.
We want to implement component related function at soc-component.c, but, some of them need to care whole snd_soc_pcm_runtime (= rtd) connected component.
Let's call component related function which need to care with for_each_rtdcom() loop as snd_soc_pcm_component_xxx(). This patch adds new snd_soc_pcm_component_pcm() and use it.

- care for_each_rtdcom() loop
