spi: Fix for v5.9

Browse source 
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) plus an update
 to MAINTAINERS reflecting Serge's extensive and detailed recent work on
 the DesignWare driver.
