[Intel-gfx] [PATCH 3/3] drm/i915: track sprite coverage and disable primary plane if possible
To save power when the sprite is full screen, we can disable the primary
plane on the same pipe. Track the sprite status and enable/disable the
primary opportunistically.

Yeah I can make ivb and snb share at least (and probably ilk), but I *do* have code coming that needs the separation. (At least I'm pretty sure; I'll remove the abstraction if it turns out I don't need it.)
