ASoC: Updates for v3.19

Lots and lots of changes this time around, the usual set of driver
updates and a huge bulk of cleanups from Lars-Peter.  Probably the most
interesting thing for most users is the Intel driver updates which will
(with some more machine integration work) enable support for newer x86
laptops.

 - Conversion of AC'97 drivers to use regmap, bringing us closer to the
   removal of the ASoC level I/O code.
 - Clean up a lot of old drivers that were open coding things that have
   subsequently been implemented in the core.
 - Some DAPM performance improvements.
 - Removal of the now seldom used CODEC mutex.
 - Lots of updates for the newer Intel SoC support, including support
   for the DSP and some Cherrytrail and Braswell machine drivers.
 - Support for Samsung boards using rt5631 as the CODEC.
 - Removal of the obsolete AFEB9260 machine driver.
 - Driver support for the TI TS3A227E headset driver used in some
   Chrombeooks.
