Revert "drm/nouveau: inform userspace of new kernel subchannel requirements"
This reverts commit a81f15499887d3f9f24ec70bb9b7e778942a6b7b. Gah, we have a released userspace component using fixed subc assignment that conflicts with this. To avoid breaking ABI this needs to be reverted. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
