On GFX11 (e.g. Navi33) that spurious SDMA\nflush can wedge the engine; only flush when a GART window is actually used.\n\nv2: Let amdgpu_ttm_map_buffer() return whether the VMID 0 flush is needed,\n    and drive the clear and copy paths from that. (Christian)\nv3: Make the vm_needs_flush output parameter mandatory instead of\n    allowing NULL.
