ASoC: soc-core: snd_soc_unregister_component() unregister all component

Current snd_soc_unregister_component() unregisters first found component only which was specified by dev. This style can't specify concrete component if system registered some component with same dev. And system need to call this function many times. This patch unregister all related component by 1 call.
