Subject: [PATCH] drm/i915/vlv: Valleyview support for forcewake Individual
 power wells.

Split vlv force wake routines to help individually control Media/Render
well based on the register access.

We've seen power savings in the lower sub-1W range on workloads that
only need on of the power wells, e.g. glbenchmark, media playback

Note: The same split isn't there for the forcewake queue, only the
forcwake domains are split.

[danvet: Rebase on top of the removed forcewake hack in the ring irq
get/put code and add a note to add Deepak's answer to Chris question.]
