Subject: [PATCH] drm/i915: Rearrange code to only have a single method for
 waiting upon the ring

Replace the wait for the ring to be clear with the more common wait for
the ring to be idle. The principle advantage is one less exported
intel_ring_wait function, and the removal of a hardcoded value.
