ASoC: use snd_kcontrol_chip() instead of

Merge series from Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>:

We would like to hide struct snd_soc_dapm_context from driver. So we need
cleanup code first. Current ASoC have very similar functions (A)(B).

	(A) snd_soc_kcontrol_component()
	(B) snd_soc_dapm_kcontrol_component()

(B) is using very picky way to get component but using it is necessary in
ASoC. But (A) is just wrapper function to snd_kcontrol_chip(), and directly
using it without wrapper is very common way on ALSA.

This patch-set doesn't merge patches for each vender etc, because it makes
backport difficult.
