All my review thus far has been aimed at reducing subsystem-wide changes
to drivers. I think we can do the full primary plane conversion without
touching drivers at all. Of course there's a bit of cleanup, but driver
maintainers can merge that at their own pace (and so avoid ugly conflicts
with ongoing work).

I'm still working on how to reduce the impact for the cursor plane
conversion as much as possible, but that's going to be fairly hard
unfortunately.
