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 Signed-off-by: Fabien Parent <fparent@baylibre.com>
