Pull ARM SoC fixes from Olof Johansson:
 "Here's a long-pending fixes pull request for arm-soc (I didn't send
  one in the -rc4 cycle).

  The larger deltas are from:

   - A fixup of error paths in the mvsdio driver

   - Header file move for a driver that hadn't been properly converted
     to multiplatform on i.MX, which was causing build failures when
     included

   - Device tree updates for at91 dealing mostly with their new pinctrl
     setup merged in 3.8 and mistakes in those initial configs

  The rest are the normal mix of small fixes all over the place; sunxi,
  omap, imx, mvebu, etc, etc."
