Merge tag 'headers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC Header cleanups from Olof Johansson:
 "This is a collection of header file cleanups, mostly for OMAP and
  AT91, that keeps moving the platforms in the direction of
  multiplatform by removing the need for mach-dependent header files
  used in drivers and other places."

Fix up mostly trivial conflicts as per Olof.
