drm/amdgpu/gfx9.4.3: set additional bits on MEC halt
Need to set the pipe reset and cache invalidation bits on halt otherwise we can get stale state if the CP firmware changes (e.g., on module unload and reload). Tested-by: Amber Lin <Amber.Lin@amd.com> Reviewed-by: Amber Lin <Amber.Lin@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
