Chris Wilson 8634d461bd sna: Limit max CPU bo size to prevent aperture thrashing on upload 
Copying between two objects that consume more than the available GATT
space is a painful experience due to the forced use of an intermediatory
and eviction on every batch. The tiled upload paths are in comparison
remarkably efficient, so favour their use when handling extremely large
buffers.

This reverses the previous idea in that we now prefer large GPU bo
rather than large CPU bo, as the render pipeline is far more flexible
for handling those than the blitter is for handling the CPU bo (at least
for gen4+).
