QEMU RISC-V supports multiple virtio devices, but only tries to boot to the first one. Enable support for a second virtio device, that is useful for instance to boot on a disk image + an installer. Ideally that should be made dynamic, but that's a first step. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Reviewed-by: Leo Yu-Chi Liang <ycliang@andestech.com>
