Update the S6000 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.
Other notable changes required for multi-component support:-
o Fix DMA params private data for playback and capture . o Removed empty s6105 audio private data. This must be platform data now.
