ASoC: More updates for v3.10

Browse source 
The main additional change here is Lars-Peter's DMA work plus the
 platform conversions which have been tested - getting this in mainline
 will make life easier for development after the merge window.  These
 factor a large chunk of code out of the drivers for the platforms using
 dmaengine, greatly simplifying development.
