the problem now is that the naming is confusing

we have snd_soc_component_del and snd_soc_del_component.
we already had snd_soc_component_add and snd_soc_add_component.

Also I find it useful to keep the _unlocked suffix when relevant, it 
adds value that is lost otherwise.

Can we avoid this pretty please?
