Pull ARM SoC platform updates from Olof Johansson:
 "This branch contains part 1 of the platform updates for 3.10.  Among
  the highlights:

   - Support for the new Atmel Cortex-A5 based platforms (SAMA5D3)
   - New support for CSR SiRFatlas6 SoCs
   - A handful of updates for NVidia T114 (a.k.a. Tegra 4)
   - A bunch of updates for the shmobile platforms
   - A handful of updates for davinci
   - A few updates for Qualcomm MSM
   - Plus a handful of other patches, defconfig updates, etc."
