[v2,01/12] ASoC: soc-component: add soc_component_pin() and share code

Commit Message

From: Kuninori Morimoto <[e-mail]>

soc-component has too many snd_soc_component_xxx_pin_xxx() functions.
The difference between these functions are used function name and
enable/disable.
This patch adds common soc_component_pin() and share code.
