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

Pull ARM SoC cleanups from Olof Johansson:
 "A smallish number of general cleanup commits this release cycle.  Some
  of these are minor tweaks:

   - shmobile change of binding for their GIC (using arm,pl390 now)
   - ARCH_RENESAS introduction
   - Misc other renesas updates

  There's also a couple of treewide commits from Masahiro Yamada
  cleaning up const/__initconst for SMP operation structs and a switch
  to using "depends on" instead of if-constructs on most of the Kconfig
  platform targets"
