Remove the optional remove callback for the soc_codec_dev_gbaudio structure. The only place it is referenced is snd_soc_component_remove() which is only called if the sound_component pointer is non-null. The null function pointers here can be optionally ommitted. When a sound component is registered this way, the remove callback is optional. We can safely remove the whole gbcodec_remove function, which used to be an empty function with a void return type.
