KMS: Explicitly specify VRAM and GTT domains when allocating BOs for pixmaps.
Without this, apparently they are initially allocated in system RAM (or
possibly GTT), so any GPU rendering to them first triggers a copy of the whole
uninitialized data to VRAM...
We may want to explore more sophisticated schemes in the future, but for now
this seems to improve KMS 2D performance quite a bit.
