OvmfPkg: add a catch-all match for PCI devices in the OpenFirmware path
In many cases, the second node in /pci@i0cf8/XYZ@DD,FF node is enough
to match a UEFI device path; a typical cases is a NIC that is assigned
from the host to the guest. Add a catch-all case for PCI devices, and
reuse it for NICs since it works well for those too.
