[Buildroot] [PATCH 1/1] board/freescale/common/imx: use nodtb variant in uboot images for 8M

[Julien Olivain]

When using u-boot.bin, u-boot is using its builtin dtb which may not
be suitable for all cases. For TechNexion Pico Pi i.MX8M and
i.MX8MMini, this break the USB and UMS commands. Since those boards
does not have SD card slots, a recovery serial download is needed at
every update.

Using u-boot-nodtb.bin now fixes this issue.
