ARM: SoC fixes for 3.13-rc
Mostly bugfixes and a few small code removals. Worth pointing out is:
- A handful of more fixes to get DT enablement working properly on OMAP,
finding new breakage of things that don't work quite right yet without
the traditional board files. I expect a bit more of this to come in this
release as people test on their hardware.
- Implementation of power_down_finish() on vexpress, to make kexec work and
to stop the MCPM core to produce a warning (the warning was new to 3.13-rc1).
- A handful of minor fixes for various platforms.
