ASoC: pxa-ssp: atomically set stream active masks

PXA's SSP engine fails to take its current channel phase into account
when enabling a stream while the engine is already running. This
results in randomly swapped left/right channels on either the record
or the playback side, depending on which one was enabled first.

The following patch fixes this by factoring out the bit field
modifications in question to a separate function that pauses the
engine temporarily, modifies the bits and kicks it off again
afterwards. Appearantly, a transition of SSCR0_SSE syncs both
directions properly.

The patch has been rolled out to quite a number of devices over the
last weeks and seems to fix the issue reliably.

Merge tag 'asoc-3.4' of git://git./linux/kernel/git/broonie/sound into topic/asoc

This has been a very active release for ASoC, as well as the usual raft
of bugfixes and driver updates there's quite a few framework enhancements.
Most are either small or are laying the groundwork for user visible
features (especially dynamic PCM), the most directly visible change is
the dmaengine library.  There's also a bunch of regmap API enhancements
pulled into the tree so that either the framework or drivers can take
advantage of the new features.

Changes include:

- Support for widgets not associated with a CODEC, an important part of
  the dynamic PCM framework.

- A library factoring out the common code shared by dmaengine based DMA
  drivers contributed by Lars-Peter Clausen.  This will save a lot of
  code and make it much easier to deploy enhancements to dmaengine.

- Support for binary controls, used for providing runtime configuration
  of algorithm coefficients.

- A new DAPM widget type for regulator supplies allowing drivers for
  devices that can power down unused supplies while active to do without
  any per-driver code.

- DAPM widgets for DAIs, initially giving a speed boost for playback
  startup and shutdown and also the basis for CODEC<->CODEC DAI link
  support.

- Support for specifying the number of significant bits on audio
  interfaces, useful for allowing applications to know how much effort to
  put into generating data for a larger sample format.

- Conversion of the FSI driver used on some SH processors to DMAEngine.

- New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics WM2200.

ASoC: core: Add support for masking out parts of coefficient blocks

Chip designers frequently include things like the enable and disable
controls for algorithms in the register blocks which also hold the
coefficients. Since it's desirable to split out the enable/disable
control from userspace the plain SND_SOC_BYTES() isn't optimal for
these devices.

Add a SND_SOC_BYTES_MASK() which allows a bitmask from the first word
of the block to be excluded from the control. This supports the needs
of devices I've looked at and lets us have a reasonably simple API.
