Hello,

this is v4 of the quest to drop the "driver" member from struct pci_dev
which tracks the same data (apart from a constant offset) as dev.driver.

Changes since v3:
 - Add some Reviewed-by and Acked-by tags
 - Rebase to v5.15-rc3 (no conflicts)
 - Changes in patch #4 addressing review comments by Christoph Hellwig

I didn't do extensive build tests, so I might have missed a build
problem. I have some builds running, but want to get some feedback on
the changes suggested by Christoph.

Best regards
Uwe
