Pull spi fixes from Mark Brown:
 "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"
