drm/i915: Add support for VGA load detection (pre-945).
Two approaches for VGA detections: hot plug detection for 945G onwards and load pipe detection for Pre-945G. Load pipe detection will get one free pipe, set border color as red and blue, then check CRT status by swf register. This is a sync-up with the 2D driver.
