These flags are tightly coupled with a PCI device and primarily used in simple binary on/off manner to check whether something is enabled or disabled, and have almost no other users (aside of two network drivers) outside of the PCI device drivers space. Therefore, convert enum pci_dev_flags into a set of bit fields in the struct pci_dev, and then drop said enum and the typedef pci_dev_flags_t. This will keep PCI device-specific features as part of the struct pci_dev and make the code that used to use flags simpler.
