Not sold on this - imo it makes more sense to keep track of this in a new
plane config structure or something similar which ties the fb + metadata
to the crtc. Then we could move a bunch of things we currently have in the
pipe config or someplaces else even (fbc, ips, ...) over there.

So I'm voting for keeping the mess a bit longer until we can do the real
thing ...
