The suballocation manager itself is not dependent on any implementation detail, and can be made generic. I want to potentially use it inside i915, as it looks like a clean implementation to do so. :) Looking for feedback and some testing, as I don't have a amdgpu/radeon myself. Only compile tested so far, so some stupid bugs may remain.
