armvirt: enable MMIO_CMDLINE_DEVICES for firecracker support
This Kernel option allows to run OpenWrt witin a `firecracker` micro VM. Firecracker is a KVM-based tool for superfast booting VMs on x86_64 and aarch64. It makes rootfs available to the guest as a virtio-mmio device and passes its address via the kernel cmdline. A kernel without CONFIG_VIRTIO_MMIO_CMDLINE_DEVICES will not recognize the rootfs virtio-mmio device. Suggested-by: Packet Please <pktpls@systemli.org> Signed-off-by: Paul Spooren <mail@aparcar.org>
