opp: Increase parsed_static_opps in _of_add_opp_table_v1()
Currently, when using _of_add_opp_table_v2 parsed_static_opps is increased and this value is used in _opp_remove_all_static() to check if there are static opp entries that need to be freed. Unfortunately this does not happen when using _of_add_opp_table_v1(), which leads to warnings. This patch increases parsed_static_opps in _of_add_opp_table_v1() in a similar way as in _of_add_opp_table_v2().
