From: "Leo (Sunpeng) Li" <sunpeng.li@amd.com>

To conform to DRM's new API, we should not be accessing a DRM object's
internal state directly. Rather, the DRM for_each_old/new_* iterators,
and drm_atomic_get_old/new_* interface should be used.

This is an ongoing process. For now, update the DRM-facing atomic
functions, where the atomic state object is given.

Andrey might be able to comment on this better, but weren't we intentionally
trying to iterate the old crtc here to make sure we send any even on it?

The states we are interested in are still the new states because that 
where the event we want
to send resides (drm_send_event_locked(dev, &crtc->state->event->base), 
with the introduction of for_each_new*
iterators we should use them to iterate the new states.

Thanks,
Andrey
