pci: recognize/report GEN4 (PCIe 4.0) card 16GT/s Link speed

Browse Source 
Without this added enum value, nodedev-dumpxml of a GEN4 (PCIe 4.0)
card will fail (due to the unrecognized link speed), and since
nodedev-detach and nodedev-reattach internally do a dumpxml+parse,
they will also fail. With this patch, all those operations succeed.
