  Modified files:
    sys/bus/pci          pci.c 
  Log:
  - Factor out pci_fixup_nextptr().
  - The checking about whether 'data' register of power management capability
    exists or not is incorrect, according to PCI local bus spec:
      1) Next capability is not necessarily at a higher location than the
         current capability.
      2) Two capabilities are not necessarily consecutive.
    Set it to 0 for now (it is not used at all) and add comment about a possible
    way to test the existence of this register in power management capability.
  - Clean up pci_read_extcap() a little bit.
