No functional difference expected atm since we default to a bottom-up allocation scheme. But that might eventually change so that we prefer the unmappable range for buffers that don't need cpu gtt access. Split out from Chris vma-bind rework. Note that this is only possible due to the split-up of the mappable pin flag into PIN_GLOBAL and PIN_MAPPABLE.
