ARM: SoC fixes for 3.13-rc

Browse Source 
Another week, another batch of fixes.
 
 Again, OMAP regressions due to move to DT is the bulk of the changes here,
 but this should be the last of it for 3.13. There are also a handful of
 OMAP hwmod changes (power management, reset handling) for USB on OMAP3
 that fixes some longish-standing bugs around USB resets.
 
 There are a couple of other changes that also add up line count a bit:
 One is a long-standing bug with the keyboard layout on one of the
 PXA platforms. The other is a fix for highbank that moves their
 power-off/reset button handling to be done in-kernel since relying on
 userspace to handle it was fragile and awkward.
