Yunxiang Li fdee0872a2 drm/amdgpu: stop tracking visible memory stats
Since on modern systems all of vram can be made visible anyways, to
simplify the new implementation, drops tracking how much memory is
visible for now. If this is really needed we can add it back on top of
the new implementation, or just report all the BOs as visible.
