drm/todo: Add entry to rename drm_atomic_state
The name of the structure drm_atomic_state is confusing. Let's add an
entry to our todo list to rename it.

For a given object (plane, CRTC, encoder, etc., so +``drm_$OBJECT_state``), the state is the entire state of that object. However, +at the device level, ``drm_atomic_state`` refers to a state update for a +limited number of objects. + +The state isn't the entire device state, but only the full state of some +objects in that device.
