spi: Updates for v4.16

Quite a quiet release for SPI, there are no changes at all to the core and not that many changes to drivers. Highlights of those driver changes include:

- SH MSIOF support for GPIO chip selects contributed by Geert Uytterhoeven.
- Full duplex support for a3700 contributed by Maxime Chevallier.
- Support for DMA transfers on Atmel devices that require a bounce buffer contributed by Radu Pirea.
