  OPP: Reuse _opp_compare_key() in _opp_add_static_v2()
  OPP: Remove rate_not_available parameter to _opp_add()
  OPP: Use consistent names for OPP table instances
  OPP: Use generic key finding helpers for bandwidth key
  OPP: Use generic key finding helpers for level key
  OPP: Add generic key finding helpers and use them for freq APIs
