ASoC: soc-component: add snd_soc_pcm_component_ioctrl()
Current ALSA SoC is directly using component->driver->ops->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_ioctrl() and use it.
