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.
