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.

+Description:
+                d3cold_allowed is bit to control whether the corresponding PCI
+                device can be put into D3Cold state.  If it is cleared, the
+                device will never be put into D3Cold state.  If it is set, the

+                value of d3cold_allowed bit.  Writing this attribute will set
+                the value of d3cold_allowed bit.

+Texas Instruments TWL family (twl4030) audio module

+The audio module inside the TWL family consist of an audio codec and a vibra
+driver.
+
+Required properties:
+- compatible : must be "ti,twl4030-audio"
+
+Optional properties, nodes:
+
+Audio functionality:
+- codec { }: Need to be present if the audio functionality is used. Within this
+             section the following options can be used:
+- ti,digimic_delay: Delay need after enabling the digimic to reduce artifacts
+                    from the start of the recorded sample (in ms)
+-ti,ramp_delay_value: HS ramp delay configuration to reduce pop noise
+-ti,hs_extmute: Use external mute for HS pop reduction
+-ti,hs_extmute_gpio: Use external GPIO to control the external mute
+-ti,offset_cncl_path: Offset cancellation path selection, refer to TRM for the
+                      valid values.
+
+Vibra functionality
+- ti,enable-vibra: Need to be set to <1> if the vibra functionality is used. if
+                   missing or it is 0, the vibra functionality is disabled.
