drm/ttm: s/FLAG_SG/FLAG_EXTERNAL/
It covers more than just ttm_bo_type_sg usage, like with say dma-buf,
since one other user is userptr in amdgpu, and in the future we might
have some more. Hence EXTERNAL is likely a more suitable name.
v2(Christian):
- Rename these to TTM_TT_FLAGS_*
- Fix up all the holes in the flag values
