ARM: soc: Fixes for 3.7-rc2

A set of fixes and some minor cleanups for -rc2:

- A series from Arnd that fixes warnings in drivers and other code
  included by ARM defconfigs. Most have been acked by corresponding

  few exception cases).

- A batch of fixes to OMAP platforms, fixing:
  - boot problems on beaglebone,
  - regression fixes for local timers
  - clockdomain locking fixes
  - a few boot/sparse warnings
- For Tegra:
  - Clock rate calculation overflow fix
  - Revert a change that removed timer clocks and a fix for symbol name clashes
- For Renesas:
  - IO accessor / annotation cleanups to remove warnings
- For Kirkwood/Dove/mvebu:
  - Fixes for device trees for Dove (some minor cleanups, some fixes)
  - Fixes for the mvebu gpio driver
  - Fix build problem for Feroceon due to missing ifdefs
  - Fix lsxl DTS files
