Fabien Parent 44165e4c67 tools: mtk_image: add support for booting ARM64 images 
mkimage is only able to package aarch32 binaries. Add support for
AArch64 images.

One can create a ARM64 image using the following command line:
mkimage -T mtk_image -a 0x201000 -e 0x201000 -n "media=emmc;arm64=1"
-d bl2.bin bl2.img
