Update the Winbond-Nuvoton platform and machines to new multi-component model.
This patch changes the machine drivers for multi-component as follows :-
o Removed socdev
o Each DAI link entry now contains platform and codec fields.
o DAI link init() now passed snd_soc_pcm_runtime instread of snd_soc_codec.
This patch also changes the DAI and platform DAM drivers as follows :-
o Each platform DAI and platform DMA driver is a kernel device and can
have platform data.
o DAI and Platform DMA drivers have private data accessors.
