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

Pull ARM SoC multiplatform support from Arnd Bergmann:
 "Converting more ARM platforms to multiplatform support.  This time,
  OMAP gets converted, which is a major step since this is by far the
  largest platform in terms of code size.  The same thing happens to the
  vt8500 platform."
