Pull spi updates from Mark Brown:
 "No framework work here, only a bunch of driver updates of varying
  sizes:

   - Factoring out of the core hardware support from the MXS MMC driver
     by Marek Vasut to allow the hardware to also be used for SPI.
   - Lots of error handling cleanups from Guenter Roeck
   - Removal of the existing Tegra driver which is quite comprehensively
     broken as detailed in the changelog for the removal.
   - DT suppport for the PL022 and GPIO drivers.
   - pinctrl support for OMAP and PL022."

Pulling from Mark Brown as Grant Likely is still busy moving.
