spi: Updates for v3.15

A busy release for both cleanups and new drivers this time along with
further factoring out of replicated code into the core:

- Provide support in the core for DMA mapping transfers - essentially
all drivers weren't implementing this properly, now there's no
excuse.
- Dual and quad mode support for spidev.
- Fix handling of cs_change in the generic implementation.
- Remove the S3C_DMA code from the s3c64xx driver now that all the
platforms using it have been converted to dmaengine.
- Lots of improvements to the Renesas SPI controllers.
- Drivers for Allwinner A10 and A31, Qualcomm QUP and Xylinx xtfpga.
- Removal of the bitrotted ti-ssp driver.
