Pull spi updates from Mark Brown:
 "Quite a busy release for SPI, mainly as a result of Boris Brezillon's
  work on improving the integration with MTD for accelerated SPI flash
  controllers. He's added a new spi_mem interface which works a lot
  better with general hardware and converted the users over to it, as a
  result of this work we've got some MTD changes in here as well.

  Other highlights include:

   - Lots of spring cleaning for the s3c64xx driver.

   - Removal of the bcm53xx, the hardware is also supported by the mspi
     driver but SoC naming had caused people to miss the duplication.

   - Conversion of the pxa2xx driver to use the standard message
     processing loop rather than open coding.

   - A bunch of improvements to the runtime PM of the OMAP McSPI driver"
