spi: Updates for v5.4

Browse source 
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.
