Looks like we have intel_atomic_prepare_commit() which I guess would be
a decent spot then. And introduce intel_atomic_cleanup_commit() to do
the reverse?

Another question is what happens where there are parallel flips
happening? One could undo the boost from the other AFAICS. But maybe
we don't care enough to protect against that?
