Freescale QSPI device tree cleanup for 4.21:
 - It contains a series from Schrempf Frieder that cleans up FSL QSPI
   device tree nodes.  The current device trees are broken because they
   use an inconsistent scheme for assigning the reg properties.  It
   becomes a problem with ongoing QSPI driver under SPI framework.  So
   the cleanup is a preparation for new driver landing in the next
   cycle.
