I created some scripts a while ago to go through the
kernel to convert struct pci_device definitions to use
PCI_VDEVICE and PCI_DEVICE.

I could move definitions out of the pci_ids.h file at
the same time and closer to their actual use if those
definitions were not globally used.  Maybe move them
by module or by specific file.

Perhaps like this example unsigned, not to be applied,
patch below:
