This should be fixed by this patch:

-------------------- drivers/gpu/drm/i915/intel_display.c ---------------------
index f553ddf..bb1b59b 100644
@@ -7675,6 +7675,7 @@ static void intel_init_display(struct drm_device *dev)
 			dev_priv->display.update_wm = NULL;
 		} else
 			dev_priv->display.update_wm = pineview_update_wm;
+		dev_priv->display.init_clock_gating = gen3_init_clock_gating;
 	} else if (IS_G4X(dev)) {
 		dev_priv->display.update_wm = g4x_update_wm;
 		dev_priv->display.init_clock_gating = g4x_init_clock_gating;

This hasn't been merged yet, but should be soon.
