This is a cutdown version of the previous [1] series containing only the ASoC
part of the edma dmaengine conversion, but without the actual switch to this new
edma-pcm platform for the McASP since the edma arch and dmaengine core changes
are needed for it to be usable.

Changes since v1:
- arch and dmaengine patches has been dropped from the ASoC series
- Patches has been reordered so only one patch is going to be needed to switch
  AM335x/AM447x to use the edma-pcm platform driver
- all comments from Lars-Peter Clausen has been addressed for the edma-pcm driver
- no changes to Kconfig/Makefile - do not yet build the edma-pcm driver. It will
  be enabled and integrated when we can do the real switch.
