spi: Updates for v4.13

There's only one big change in this release but it's a very big change,
Geert Uytterhoeven has implemented support for SPI slave mode. This
feature has been on the cards since the subsystem was originally merged
back in the mists of time so it's great that Geert stepped up and
finally implemented it.

- SPI slave support, together with wholesale renaming of SPI
controllers from master to controller which went surprisingly
smoothly. This is already used with Renesas SoCs and support is in
the works for i.MX too.
- New drivers for Meson SPICC and ST STM32

Amelie Delaunay (10):
spi: Document the STM32 SPI bindings
spi: add driver for STM32 SPI controller
spi: stm32: use SoC specific compatible
spi: stm32: fix compatible to fit with new bindings
spi: stm32: fix example with st, spi-midi-ns property
spi: stm32: replace st, spi-midi with st, spi-midi-ns to fit bindings
spi: stm32: use normal conditional statements instead of ternary operator
spi: stm32: add runtime PM support
spi: stm32: enhance DMA error management
spi: stm32: fix potential dereference null return value
