tests/libqos: pci-spapr driver and interface nodes
Add pci-bus-spapr node, that produces pci-bus. Move QPCIBusSPAPR struct declaration in its header (since it will be needed by other drivers) and introduce a setter method for drivers that do not need to allocate but have to initialize QPCIBusSPAPR.
