Afaict this has been used for two things:
- To prevent the crtc enable code from being run twice. We have now
intel_crtc->active to track this in a more precise way.
- To ensure the code copes correctly with the unknown hw state after
boot and resume. Thanks to the hw state readout and sanitize code we
have now a better way to handle this.
The only thing it still does is complicate our modeset state space.
Having outlived its usefullness, let it just die.
