ARM: SoC low-priority fixes for 3.12 

This branch contains a handful of fixes for various platforms that
 weren't serious enough to be included in late 3.11-rc releases. Most of
 them are for minor cleanups and cosmetic fixes.
 
 There's also a bit of code removal here, one board file removal for
 clps711x, and removal of some legacy device creation on OMAP2+.
