        drm/i915: factor out GMCH panel fitting code and use for eDP v3
    
    broke that by reordering the computation of the gmch pfit state with
    the block of code that prepared the adjusted mode for it and told the
    modeset core not to overwrite the adjusted mode with default settings.
    
    We might want to switch around the core code to just fill in defaults,
    but this code predates the pipe_config modeset rework. And in the old
    crtc helpers we did not have a suitable spot to do this.
