PCI: Add decoding for 16 GT/s link speed
PCIe 4.0 defines the 16.0 GT/s link speed. Links can run at that speed
without any Linux changes, but previously their sysfs "max_link_speed" and
"current_link_speed" files contained "Unknown speed", not the expected
"16.0 GT/s".
Add decoding for the new 16 GT/s link speed.
