mb/emulation/qemu-aarch64: Add ARM trusted firmware support
Linux expects a working PSCI and hangs if not found.
Add BL31 into CBFS as '-M virt,secure=on -bios ' commands line arguments cause
qemu's internal PSCI emulation to shutdown.
BL31 is placed in qemu's SECURERAM memory region and won't conflict with
resources in DRAM.
Tested on qemu-system-aarch64:
Fixes a hang and allows to boot into Linux 5.4.14 userspace.
