drm: Merge __drm_atomic_helper_disable_all() into drm_atomic_helper_disable_all()
The only difference between the functions is the clean_old_fbs argument, whose
use was removed in the patch referenced below. So remove the internal
copy and drop the guts back into drm_atomic_helper_disable_all()
Changes in v2:
- Instead of just removing the unused arg, merge the functions
Fixes: e00fb8564ee9 ("drm: Stop updating plane->crtc/fb/old_fb on atomic drivers")
