drm/display/dp_mst: Add drm_atomic_get_old_mst_topology_state()
Add a function to get the old MST topology state, required by a
follow-up i915 patch.
While at it clarify the code comment of
drm_atomic_get_new_mst_topology_state() and add _new prefix
to the new state pointer to remind about its difference from the old
state.
v2: Use old_/new_ prefixes for the state pointers. (Ville)
