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.
