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

Pull ARM SoC multiplatform conversion patches from Olof Johansson:
 "Here are more patches in the progression towards multiplatform, sparse
  irq conversions in particular.

  Tegra has a handful of cleanups and general groundwork, but is not
  quite there yet on full enablement.

  Platforms that are enabled through this branch are VT8500 and Zynq.
  Note that i.MX was converted in one of the earlier cleanup branches as
  well (before we started a separate topic for multiplatform).  And both
  new platforms for this merge window, sunxi and bcm, were merged with
  multiplatform support enabled."

Fix up conflicts mostly as per Olof.
