Emanuele Giuseppe Esposito 57ed038ad9 tests/libqos: virtio-mmio driver and interface nodes
Add virtio-mmio node in qgraph framework.
virtio-mmio produces virtio-bus, the interface consumed by all virtio-*-device
nodes.

Being a memory-mapped device, it doesn't have to provide a constructor
to qgraph, since it's always "contained" inside some other nodes.
