Pull spi fix from Mark Brown:
 "One last minute fix for v5.9 which has been causing crashes in test
  systems with the fsl-dspi driver when they hit deferred probe (and
  which I probably let cook in next a bit longer than is ideal).

  And an update to MAINTAINERS reflecting Serge's extensive and
  detailed recent work on the DesignWare driver"
