Subject: [PATCH] drm/i915: Don't downclock whilst we have clients waiting for
 GPU results

If we have clients stalled waiting for requests, ignore the GPU if it
signals that it should downclock due to low load. This helps prevent
the automatic timeout from causing extremely long running batches from
taking even longer.
