ASoC: Updates for v3.10

A bunch of changes here, the most interesting one subsystem wise being
Morimoto-san's work to create snd_soc_component which doesn't do much
for now but will be pretty important going forwards:

 - Add a new component object type which will form the basis of moving
   to a more generic handling of SoC and off-SoC components, contributed
   by Kuninori Morimoto.
 - A fairly large set of cleanups for the dmaengine integration from
   Lars-Peter Clausen, starting to move towards being able to have a
   generic driver based on the library.
 - Performance optimisations to DAPM from Ryo Tsutsui.
 - Support for mixer control sharing in DAPM from Stephen Warren.
 - Multiplatform ARM cleanups from Arnd Bergmann.
 - New CODEC drivers for AK5385 and TAS5086 from Daniel Mack.
