I don't see a need to move that stuff anywhere. Just leave it
in hsw_crtc_enable() IMO.

This is what I have been suggesting.

But I think there's also some per-pipe stuff currently in the
the encoder hooks, and some of that is only done for the master
there whereaas the slave part I think are somewhere else. We
should attempt to fix that as well so that every step is done
in a consistent manner for every pipe be it master or slave.
