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

Pull ARM SoC cleanups from Olof Johansson:
 "The cleanup branch keeps going down in size as we've completed a lot
  of the major legacy platform removals and conversions.

  A handful of changes this time around, some of the themes or larger
  sets are:

   - A bunch of i.MX cleanups around platform detection, init call cleanups
   - Misc fixes of missing/implicit includes
   - Removal of ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB"
