[PATCH v2] config: Add 'update_bootimg' command to update flash.bin on Phytec's imx8mm

This command allows easy update on SD card or eMMC of the flash.bin generated (with binman) during u-boot build.

As Benjamin pointed out earlier this increment by one is not necessary.
All other i.MX8M docs don't have this increment.

So apparently the BSP build scripts in OE/Yocto take always care to have 0x200 aligned binaries (imx-boot and flash.bin).
OK, I will remove it.
