A few more ASoC updates, the main one is the move of the audmux driver
from arch/arm into sound/soc.  There's also some general driver specific
tweaks and fixes.

It adds device tree probe support for imx-audmux driver.

Currently ASoC:imx uses menuconfig option SND_IMX_SOC selects imx-ssi
driver, and it works because all the machine driver covered by the
menuconfig need to build imx-ssi driver in.  However, it will not work
any more if we have a imx based machine driver going into the menuconfig
while working with fsl_ssi driver (sound/soc/fsl/fsl_ssi.c) rather than
imx-ssi one.

The patch adds an explicit Kconfig option SND_SOC_IMX_SSI for imx-ssi
driver, so that it can be selected independently from the menuconfig
option SND_IMX_SOC.

Currently the imx-ssi.c[h] accommodates the imx-pcm common bits which
are shared between imx-pcm-dma-mx2 and imx-pcm-fiq drivers.  It assumes
that imx-pcm-dma-mx2 and imx-pcm-fiq will always be used together with
imx-ssi driver.  However this becomes untrue when we see that driver
sound/soc/fsl/fsl_ssi could possibly work with imx-pcm-dma-mx2 too.

The patch moves the imx-pcm common bits from imx-ssi.c[h] into new
files imx-pcm.c[h], and let imx-pcm-dma-mx2 and imx-pcm-fiq drivers
build it in, so that imx-pcm-dma-mx2 can work with no dependency on
imx-ssi driver.

As audmux becomes a platform driver and its callers are all ASoC
machine drivers, there is no reason to keep it in arch folder, so
move it to sound/soc/imx.

One bonus point would be those ASoC machine drivers stop including
mach/audmux.h, since it's been moved to sound/soc/imx/imx-audmux.h.
This should be a move to the right direction in terms of single kernel
image goal.

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.

Without that fix the wm8753 SPI initialization fails, and then produces
  a kernel panic during boot with the following call trace:

There's now core code which falls back to global CODEC operations for
DAI calls that needs to be able to tell if it's dealing with a CPU or
CODEC DAI and given the small number of DAIs in a typical system and
overall memory usage pattern saving a pointer per DAI is really not
worth the effort.
