That's an awful lot of additional LoC for what is primarily
a refactoring job with the intent to simplify things.

Honestly this looks like an attempt to fix something that
isn't broken.  Specifically, the is_thunderbolt bit apparently
can't be removed without adding new bits to struct pci_dev.
Not sure if that can be called progress.

Thanks,

Lukas
