use dmaengine for atmel ssc/pcm dai drivers

[Nicolas Ferre]

This patch series is built on top of ASoC git tree for-3.1 branch.

It will add the DMA use through dmaengine to the SSC/PCM Atmel drivers. These
drivers are curently using the PDC DMA feature which has been replaced by a DMA
controller in some chips. The dmaengine driver curently used is at_hdmac.

The first patch is a little update to wm8731 codec driver.

Nicolas Ferre (5):
      ASoC: wm8731: rework power management
      ASoC: atmel-ssc: add phybase in device structure
      ASoC: atmel-ssc: dmaengine usage switch depending on cpu
      ASoC: atmel_ssc_dai/atmel-pcm: adapt to dmaengine usage
      ASoC: atmel_ssc_dai: PM: actually stopping clock on suspend/resume
