[PATCH v5 05/12] ASoC: soc-component: add snd_soc_component_{set/to}_priv()

struct snd_soc_component will be capsuled soon, its member will not be
able to access from non soc-component.c.

Basically, each drivers are using dev_{set/get}_drvdata() to set own data,
but it is not enough. Let's add .priv.

Add snd_soc_component_{set/to}_priv() to access priv.
