bsp: Rewrite stage2-linux by copying what mkroot (formerly Aboriginal) does

This produces an armv8l64 system which boots in QEMU with the following
commandline:

    qemu-system-aarch64 -M virt -cpu cortex-a57 -nographic -no-reboot -m 256 \
        -append "panic=1 HOST=aarch64 console=ttyAMA0"
        -kernel ./linux-armv8l64/boot/Image
