[PATCH v2 06/12] ASoC: soc-component: add snd_soc_pcm_component_hw_params()

[Kuninori Morimoto]

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

We have 2 type of component functions
snd_soc_component_xxx()     is focusing to component itself,
snd_soc_pcm_component_xxx() is focusing to rtd related component.

Now we can update snd_soc_component_hw_params() to
snd_soc_pcm_component_hw_params(). This patch do it.
