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.
