In a way, yes. But in the best case we should have the same code in both
places (now it's copied), and also should be able to check which parts of
the hw we actually need (since the get_hw_state now hides the
cpu_transcoder in between the ddi and the pipe that's not so easy to do).
So I still think we should try to unify/improve this a bit, especially
since for the other fastboo stuff we need more cleverness for pipe state
anyway (otherwise handling plls&friends will be a pain).
