drm/ttm: initialize globals during device init (v2)
Make sure that the global BO state is always correctly initialized. This allows removing all the device code to initialize it. v2: fix up vbox (Alex) Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Junwei Zhang <Jerry.Zhang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
