[PATCH] ARM: dts: imx: Fix eMMC boot on Data Modul i.MX8M Plus eDM SBC

[Marek Vasut]

In case the i.MX8M Plus starts from eMMC BOOT1/BOOT2 HW partitions, the
flash.bin container is stored at offset 0 from the start, that means the
fitImage itb is at offset 0x2c0 instead of 0x300 sectors from the start.
Handle this difference in custom spl_mmc_get_uboot_raw_sector() .
