----------------------------------------------------------------
spi: Updates for v5.4

The big theme for this release has been performance, we've had a series
of unrelated overhauls of a few drivers all with a big peformance
component. Otherwise it's been relatively quiet, highlights include:

- A big overhaul of the spi-fsl-dspi driver improving the code quality,
performance and stability from Vladimir Oltean.
- A big performance enhancement for the bc2835 (Raspberry Pi) driver
for unidirectional transfers from Lukas Wunner.
- Improved performance on small transfers for the uniphier driver from
Keiji Hayashibara.
- Lots of coccinelle generated cleanups from Yue Haibing.
- New device support for Freescale ls2080a and Nuvoton NPCM FIU.
