drm: Fix up drm_atomic_state_helper.[hc] extraction
I've misplaced two functions by accident:
- drm_atomic_helper_duplicate_state is really part of the
resume/suspend/shutdown device-wide helpers.
- drm_atomic_helper_legacy_gamma_set is part of the legacy ioctl
compat helpers.
Move them both back.
Fixes: 9ef8a9dc4b
