drm/i915: set IDICOS to medium uncore resources
I'm seeing about a 5% FPS improvement across various benchmarks on my IVB i3. Rumor has it that the higher end parts show even more benefit. This derives from a patch originally given to me by Bernard. The docs are confusing about the definition names (ie. medium really seems like max), but it would seem it gives more cache to the GT at the expense of uncore. This configuration makes the split most in favor of the GT. I've not tried the other IDICOS values.
