spi: Fixes for v4.19

Browse source 
Quite a few fixes for the Renesas drivers in here, plus a fix for the
 Tegra driver and some documentation fixes for the recently added spi-mem
 code.  The Tegra fix is relatively large but fairly straightforward and
 mechanical, it runs on probe so it's been reasonably well covered in
 -next testing.
