Yes, it will simplify things. Lets assume you see that some NetBSD
committer added new ID's to the driver which uses ID's in the match code.
At the moment you have to:

- Check from NetBSD pcidevs what are the numeric ID's for these devices.
- Check if these entries can be used in our pcidevs file. If not, resolve
  the conflicts.
- Commit pcidevs.
- Regenerate pcidevs.h and pcidevs_data.h and edit driver to add new
  entries.
- Commit pcidevs.h, pcidevs_data and driver.

Without pcidevs:

- Check from NetBSD pcidevs what are the numeric ID's for these devices.
- Edit driver to add new entries.
- Commit the driver.
