spi: Fixes for v6.10

Browse source

A series of fixes that came in since the merge window, the main thing
 being the fixes Andy did for DMA sync where we were calling into the DMA
 API in suprising ways and causing issues as a result, the main thing
 being confusing the IOMMU code.
 
 We've also got some fairly important fixes for the stm32 driver, it
 supports a wide range of hardware and some optimisations that were done
 recently have broken on some systems, and a fix to prevent glitched
 signals on the bus in the cadence driver.
