ASoC: soc-component: unpack snd_soc_component_get_bias_level()

Because struct snd_soc_dapm_context is soc-dapm framework specific, user
driver don't need to access its member directly, we would like to hide
them. struct snd_soc_dapm_context will be removed from header in the
future.

This patch unpack component wrapper to cleanup it.

The function will be kept by using macro for a while, but will be
replaced/cleanuped in the future.
