[PATCH 21/24] ASoC: soc-component: add snd_soc_component_init()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

we wantn't to directly access to component related parameter
as much as possible to keep encapsulation.
This patch adds snd_soc_component_init() for it.
