Merge tag 'spi-fix-v4.5-rc4' into spi-imx

spi: Fixes for v4.5

A small clutch of driver specific fixes.  The OMAP one is a bit worrying
since it seems to be triggered by some changes in the runtime PM core
code and I suspect there's other drivers across that are going to be
using the same pattern outside of OMAP but nothing seems to be coming up
in the testing people are doing.
