Yeah that amdgpu destruction code kinda stinks a little bit :\. I think we can
just drop some of it and move the rest into their connector destruction
callbacks.

For the whole series:

I'm going to go ahead and let the maintainers know I'm going to push this
(since there's some minor changes here outside of drm-misc), and push this to
drm-misc-next. Then I'll go and write some patches to remove the leftover amd
bits and drop the callback for good (I'll cc it to you as well).
