drm: Add checks for atomic_[duplicate/destroy]_state with atomic drivers

This patch add checks for atomic_[duplicate/destroy]_state of
drm_[connector/crtc/plane]_funcs for atomic drivers in the relevant
drm_*_init functions since these callback are mandatory for atomic drivers.

Update the kerneldoc comments for those callbacks.
