  Add SPI Driver to HPE GXP Architecture (2022-07-29 20:22:22 +0100)

spi: Updates for v5.20

The big update this time around is some excellent work from David Jander
who went through the fast path and really eliminated overheads, meaning
that we are seeing a huge reduction in the time spent between transfers
for single threaded clients. Benchmarking has been coming out at about a
halving of overhead which is clearly visible in system level usage that
stresses SPI like some CAN and IIO applications, especially with small
transfers. Thanks to David for taking the time to drill down into this
and push the work upstream.

Otherwise there's been a bunch of new device support and the usual

 - Optimisation of the fast path, particularly around the number and
   types of locking operations, from David Jander.
 - Support for Arbel NPCM845, HP GXP, Intel Meteor Lake and Thunder Bay,
   MediaTek MT8188 and MT8365, Microchip FPGAs, nVidia Tegra 241 and
   Samsung Exynos Auto v9 and 4210.
