P2P: Allow P2P client to specify preferred group channel
When re-invoking a persistent group in P2P client role, the new pref=<MHz> parameter can now be used with the p2p_invite command to indicate a preferred operating frequency. Unlike the older freq=<MHz> parameter, this leaves GO an option to select another channel (from our supported channels) if the GO cannot accept the channel.
