P2P: Add a conf parameter to start a GO as HT40 if allowed

Browse Source 
When specified in the conf file this parameter will make all invocations
of p2p_group_add, p2p_connect, and p2p_invite behave as if "ht40" has
been specified on the command line. This shouldn't do harm since
regulatory constraints and driver capabilities are consulted anyway
before starting HT40 mode.
