Kuninori Morimoto 29926fc8e8 ASoC: codec duplicated callback function goes to component on sta529 
codec driver and component driver has duplicated callback functions,
and codec side functions are just copied to component side when
register timing. This was quick-hack, but no longer needed.
This patch moves these functions from codec driver to component driver.
