qemu vfio-pci: PCIe and generic config space mangling

v2: Removing trailing \n from error_report calls

This series generalizes the places where we already rely on QEMU config space emulation to make it easier to add various other fields. It turns out that when we start running on Q35 Windows cares quite a bit about the PCIe type we expose. Drivers will fail to load if not set to something valid and appropriate for the bus. We don't have anything in place yet to tell what the bus is, so for now we rely on a temporary option that will eventually get replaced by something automatic. Thanks,

Alex
