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.
