- Add some registers defined in PCI 3.0 including new AER bits. - Add constants for the rest of the fields in the PCI-express device   capability and control registers. - Tweak some of the recently added PCI-e capability constants (always   use hex for offsets in config space, and include a shortened   version of the relevant register in the name of field constants).
