ASoC: Updates for v3.7

Lots and lots of driver specific cleanups and enhancements but the only
substantial framework feature this time round is the compressed API
binding:

- Addition of ASoC bindings for the compressed API, used by the mid-x86
  drivers.
- Lots of cleanups and API refreshes for CODEC drivers and DaVinci.
- Conversion of OMAP to dmaengine.
- New machine driver for Wolfson Microelectronics Bells.
- New CODEC driver for Wolfson Microelectronics WM0010.
