[PATCH V2 1/2] imx: imx8mm-beacon: Enable FlexSPI in U-Boot

[Adam Ford]

In order to use the FlexSPI interface in U-Boot, configure
the alias to make spi0 point to flexspi.

With that enabled, sf probe detects the QSPI part as:
SF: Detected n25q256ax1 with page size 256 Bytes, erase size 4 KiB, total 32 MiB

[PATCH V2 2/2] configs: imx: imx8mm_beacon: Add config option for QSPI booting

[Adam Ford]

The imx8mm_beacon SOM has a QSPI part attached to the FSPI controller.
Update the header and spl files to support booting from NOR flash and
add imx8mm_beacon_fspi_defconfig to support this configuration.
