From: Ville Syrjälä <ville.syrjala at linux.intel.com>

This is an attempt at more or less finish the bigjoiner
state computation/readout refactoring.

Stuff that should now be in decent shape:
- cursor should appear in the right spot on all pipes
- plane clipping/etc. independent of number of joined pipes
  thanks to the PIPESRC drm_rect
- the PIPESRC drm_rect should prove helpful for the seam
  elimination stuff too in the future, as well as for some
  other planned scaler fixes/cleanups
- bigjoiner vs. MSO timings should be properly handled now

What is likely still busted:
- panel fitter. The state computation needs to be redesigned fully
  for bigjoiner. Semi-related to the aforementioned scaler work.
- the modeset sequence is still a huge mess. That will have
  to be the next major refactoring target I think.

Pushed the lot here:
