net: add virtio network driver
This gives virtio-enabled boards an easy route to network connectivity:
qemu-system-aarch64 -M virt -serial mon:stdio -trace file=/dev/null \
-kernel images/barebox-dt-2nd.img -cpu cortex-a57 -nographic \
-device virtio-net-device,netdev=network0 -netdev tap,id=network0,ifname=tap0
The tap0 interface created by QEMU can then be bridged/listened on.
