spi: Fixes for v6.11

Browse Source 
A few small driver specific fixes (including some of the widespread work
 on fixing missing ID tables for module autoloading and the revert of
 some problematic PM work in spi-rockchip), some improvements to the
 MAINTAINERS information for the NXP drivers and the addition of a new
 device ID to spidev.
