[Intel-gfx] [PATCH 02/13] drm/i915: Virtualize the ringbuffer signal func

This abstraction again is in preparation for gen8. Gen8 will bring new semantics for doing this operation. While here, make the writes of MI_NOOPs explicit for non-existent rings. This should have been implicit before. NOTE: This is going to be removed in a few patches. Reviewed-by: Ville Syrjäl
