ASoC: soc-component: add snd_soc_component_regmap_val_bytes()

Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> says:

component has component->val_bytes which is set via
snd_soc_component_setup_regmap(). But it can be calculated via
component->regmap. No need to keep it as component->val_bytes.

This patchset adds new snd_soc_component_regmap_val_bytes(),
and remove component->val_bytes / snd_soc_component_setup_regmap().
