Second version of the patch. I didn't fix the copyright (which ame up
in the previous version), as I feel the original author should send a
patch for that.
I've made the suballocator into its own module, and did a cleanup pass on it.
The suballocator is generic enough to be useful for any resource that can be
subdivided and is guarded by a completion fence.
Well the main issue is still that you removed the per allocation alignment.
For amdgpu that is not much of a problem, but for radeon that could
cause massive issues with UVD semaphore synchronization.

drm: Extract amdgpu_sa.c as a generic suballocation helper
drm/amd: Convert amdgpu to use suballocation helper.
drm/radeon: Use the drm suballocation manager implementation.
