Pull ARM SoC platform updates from Olof Johansson:
 "SoC changes, a substantial part of this is cleanup of some of the
  older platforms that used to have a bunch of board files.

  In particular:

   - Remove non-DT i.MX platforms that haven't seen activity in years,
     it's time to remove them.

   - A bunch of cleanup and removal of platform data for TI/OMAP
     platforms, moving over to genpd for power/reset control (yay!)

   - Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
     closer to multiplatform support (not quite there yet, but getting
     close).

  There are a few other changes too, smaller fixlets, etc. For new
  platform support, the primary ones are:

   - New SoC: Hisilicon SD5203, ARM926EJ-S platform.

   - Cpufreq support for i.MX7ULP"
