[PATCH 3/3] arch: arm: imx: spi: Add QSPI boot option to the IMX8MN-EVK

[Joacim Zetterling]

Add lowlevel board functionality to be able to boot from
a QSPI device.

Also added configuration parameters for a QSPI device to be
included in a final QSPI boot image.
All configuration for a QSPI boot image are controlled within
the board flash header configuration file.
