We usually don't add things to pci_ids.h unless they're used in more
than one place (see the comment at the top of the file).  AFAICT,
these device IDs are only used in one file, so you can leave the
#defines in the file that uses them or use bare hex values.

These device IDs are all in https://pci-ids.ucw.cz/read/PC/19e5
already, thanks for that!
