ARM64: specify external firware binary for containerized qemu

Browse Source 
Current implementation uses a fixed firmware(bios) binary
installed by the build process of the qemu container image,
which will prevent us from providing an external firmware binary
outside the container. This patch removes this limitation, thus we
can assign a firware binary image file with "-fw" option.
