Unify BO evicting functionality for VRAM and TT memory
types in amdgpu_object.c. Use amdgpu_bo_evict_gtt()
for evicting gtt memory similar to how we do that
for amdgpu_debugfs_evict_vram().

That function should probably be inside amdgpu_ttm.c instead.

At least in theory we could do that for OA, GWS and GDS as well.

I won't add a wrapper for that. This looks like misplaced and overkill.
