drm: bridge: Mark deprecated operations in drm_bridge_funcs 

drm_bridge_funcs includes several duplicated operations as atomic
variants have been added over time.
New bridge drivers shall use the atomic variants - mark the deprecated
operations to try to avoid usage in new bridge drivers.

v2:
  - Drop out-dated comment about state in mode_set (Laurent)
  - Added missing "the" in a description
