This adds all the current gen9 pci ids that were missing :
- Some new coffee lake, kaby lake and whiskey lake ids
- Comet lake ids (which is also gen9 but not yet supported by drm-devel-kmod)
Ok, but this pci_early_stuff shall be removed from the kernel. It was added with the promise that eventually code will be finished (by outguessing broken BIOSes and reserving the phys memory before VM takes hold on it). This never happen and right now it is just space taken in the kernel text.
It would live a more happy life in the driver instead.
