Makefiles: add a i.MX8 flash.bin target

This is taken from the soc.mak makefile. It relies on an OE deploy dir with
the relevant boot binaries. See mx8_boot_img/Makefile for where the
mkimage-imx8 and the various boot binaries are taken from.

use 'make flash.bin' to build U-Boot and then build the boot image.
To flash use:
dd if=flash.bin of=${SDCARD} conv=notrunc seek=33 bs=1K
