pci: include a minimum pci.ids with classes, note when pci.ids is missing

Noticed that the RPi4 has a PCIe bus, but pci.ids is not included with
the standard Raspbian image, so everything is "(Unknown)."
Now there will be some basic information about what the device is, and
a note about installing pci.ids for more information.
