ASoC: Updates for v3.13

 - Further work on the dmaengine helpers, including support for
   configuring the parameters for DMA by reading the capabilities of the
   DMA controller which removes some guesswork and magic numbers fromm
   drivers.
 - A refresh of the documentation.
 - Conversions of many drivers to direct regmap API usage in order to
   allow the ASoC level register I/O code to be removed, this will
   hopefully be completed by v3.14.
 - Support for using async register I/O in DAPM, reducing the time taken
   to implement power transitions on systems that support it.
