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

Pull ARM SoC cleanups from Olof Johansson:
 "We've got a fairly large cleanup branch this time.  The bulk of this
  is removal of non-DT platforms of several flavors:

   - Atmel at91 platforms go full-DT, with removal of remaining
     board-file based support

   - OMAP removes legacy board files for three more platforms

   - removal of non-DT mach-msm, newer Qualcomm platforms now live in
     mach-qcom

   - Freescale i.MX25 also removes non-DT platform support"

Most of the rest of the changes here are fallout from the above, i.e. for
example removal of drivers that now lack platforms, etc.
