- Add a few more register defintions for the PCI express capability
registers. - Cleanup PCI-X capability printf to not leave a dangling "supports" for some PCI-X bridges. - Display additional PCI express details including the negotiated and max link width and the actual and maximum supported max payload. MFC after: 1 month
