ASoC: Updates for 3.6

A bigger set of updates than I'm entirely comfortable with - things
backed up a bit due to travel.  As ever the majority of these are small,
focused updates for specific drivers though there are a couple of core
changes.  There's been good exposure in -next.

The AT91 patch fixes a build break.
