spi: Updates for v4.9

The SPI subsystem has also had quite a quiet release, though with a
fairly large set of per-driver changes and several new drivers. The
bulk of the changes are:

- Lots and lots of cleanups and improvements for the fsl-espi driver.
- New drivers for Broadcom MSPI/iProc/STB, Cavium ThunderX and J-Core.
