Add QSPI support in the default config and DTS files for the
NXP IMX8MN-EVK board. To be able to use it You also need the
QSPI driver enabled.
Tested on the NXP IMX8MN-EVK board as well as on an IMX8MN
custom bord supporting a QSPI flash. Tested with the memory
dump command i.e. 'md -s /dev/m25p0'.
