The main things here are that each pipe now does full clock computation/readout with its own shared_dpll reference. Also every pipe's cpu_transcoder always points correctly at the master transcoder. Due to the above changes state readout is now complete and all the related hacks can go away. The actual modeset sequence code is still a mess, but I think in order to clean that up properly we're probably going to have to redesign the modeset logic to treat transcoders vs. pipes separately. That is going to require significant amounts of work.
