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

Pull ARM soc multiplatform enablement from Olof Johansson:
 "This is a pretty significant branch.  It's the introduction of the
  first multiplatform support on ARM, and with this (and the later
  branch) merged, it is now possible to build one kernel that contains
  support for highbank, vexpress, mvebu, socfpga, and picoxcell.  More
  platforms will be convered over in the next few releases.

  Two critical last things had to be done for this to be practical and
  possible:
   * Today each platform has its own include directory under
     mach-<mach>/include/mach/*, and traditionally that is where a lot
     of driver/platform shared definitions have gone, such as platform
     data structures.  They now need to move out to a common location
     instead, and this branch moves a large number of those out to
     include/linux/platform_data.
   * Each platform used to list the device trees to compile for its
     boards in mach-<mach>/Makefile.boot.

  Both of the above changes will mean that there are some merge
  conflicts to come (and some to resolve here).  It's a one-time move
  and once it settles in, we should be good for quite a while.  Sorry
  for the overhead."

Fix conflicts as per Olof.
