Move Wolfson CODECs to multi-component model.
This patch changes the probe() and remove() of the CODEC drivers as follows:-
o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec(). o codec cache can now be malloc()ed by core.
Other required changes due to multi-component model :-
o wm8993: set_fll() needs to be accessed from both codec and dai device context, so wrapper added to acces from dai context.
