Mark Brown 5998102b90 ASoC: Refactor WM8731 device registration
Move the WM8731 driver to use a more standard device registration
scheme where the device can be registered independantly of the ASoC
probe.

As a transition measure push the current manual code for registering
the WM8731 into the individual machine driver probes. This allows
separate patches to update the relevant architecture files with less
risk of merge issues.

Mark Brown 7ee7538041 ASoC: Rename AT91SAMG20-EK for applications
This is a bit more idiomatic and makes identifying a configuration
based on the board type work better.

Mark Brown 5de7f9b200 ASoC: Actively manage MCLK for AT91SAM9G20-EK
We have software control of the MCLK for the WM8731 so save a bit of
power by actively managing it within the machine driver, enabling it
only while the codec is active.

Once ASoC supports multiple boards and doesn't require the soc-audio
device the initial clock setup should be pushed down into the arch/arm
code but for now this reduces merge issues.

Mark Brown d694354115 ASoC: Improve diagnostics for AT91SAM9G20-EK probe
We should display an error by default if we fail to register.

Mark Brown 87689d567a ASoC: Push platform registration down into the card
As part of the deprecation of snd_soc_device push the registration of
the platform down into the card structure.

Mark Brown 875065491f ASoC: Rename snd_soc_card to snd_soc_machine
One of the issues with the ASoC v1 API which has been addressed in the
ASoC v2 work that Liam Girdwood has done is that the ALSA card provided
by ASoC is distributed around the ASoC structures. For example, machine
wide data such as the struct snd_card are maintained as part of the
CODEC data structure, preventing the use of multiple codecs. This has
been addressed by refactoring the data structures so that all the data
for the ALSA card is contained in a single structure snd_soc_card which
replaces the existing snd_soc_machine and snd_soc_device.

Begin the process of backporting this by renaming struct snd_soc_machine
to struct snd_soc_card, better reflecting its function and bringing it
closer to standard ALSA terminology.

Add audio support for the Atmel AT91SAM9G20ek board(uing wolfson 8731).
It is based on the former eti_b1_wm8731.c file, using the atmel scc API.
