…arm-soc

Pull support for new arm SoCs from Olof Johansson:
 "Three new system-on-chip models are supported: the st-ericsson u9540
  in ux500, the sam9n12 in at91 and the emma ev2 in shmobile.

  Emma is a little bit special because it is completely unrelated to the
  classic shmobile models, but the new Renesas rmobile SoCs are a
  combination of things from both Emma and shmobile, so it was decided
  to have them all live in one directory.

  This also contains updates to existing shmobile soc code as well as
  some related board changes due to dependencies."
