  Log:
  Fix the subvendor ID for PCI-PCI bridges.
  - Retire the PCI_SUB*_1 constants and don't try to read a subvendor ID out
    of them.  There isn't a standard subvendor ID field for PCI-PCI bridges.
    Instead, the dword at offset 0x34 is actually mostly reserved except for
    the LSB which is the capabilities pointer.
  - Add support for the PCI-PCI bridge subvendor ID capability (13) and use
    it to set the subvendor ID for PCI-PCI bridges.
