Chris Wilson 7b334fcb45 drm: Use a nondestructive mode for output detect when polling 
Destructive load-detection is very expensive and due to failings
elsewhere can trigger system wide stalls of up to 600ms. A simple
first step to correcting this is not to invoke such an expensive
and destructive load-detection operation automatically.
