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

Pull ARM SoC cleanups on various subarchitectures from Olof Johansson:
 "Cleanup patches for various ARM platforms and some of their associated
  drivers.  There's also a branch in here that enables Freescale i.MX to
  be part of the multiplatform support -- the first "big" SoC that is
  moved over (more multiplatform work comes in a separate branch later
  during the merge window)."

Conflicts fixed as per Olof, including a silent semantic one in
arch/arm/mach-omap2/board-generic.c (omap_prcm_restart() was renamed to
omap3xxx_restart(), and a new user of the old name was added).
