mb/emulation/qemu-armv8: Add new board for ARMv8

Ported the ARMv7 board to ARMv8.
Added custom bootblock, as the memory mapped NOR flash shouldn't be
written to. The bootblock relocates itself to SRAM.

Tested on QEMU:
qemu-system-aarch64 -M vexpress-a9 -cpu cortex-a53 -m 1024 \
 -bios build/coreboot.rom -nographic
