Pull spi updates from Mark Brown:
 "Quite an active release for the SPI subsystem, lots of small updates
  and fixes scattered about with highlights including:

   - 3-wire support in the GPIO driver.

   - support for setting a custom memory name in the memory mapped flash
     drivers.

   - support for extended mode in the Freescale DSPI controller.

   - support for the non-standard integration with the Microsemi Ocelot
     platform in the DesignWare driver.

   - new driver for the SocioNext UniPhier"
