P2P: add conf param to prefer p2p multi channel
When p2p_multi_chan=1 is set in the wpa_supplicant.conf file, don't set
the P2P operating channel according to any existing shared frequency.
Normally we would force the operating channel to be the same as that of
other interfaces operating on the same phy. This param allow us to optimize
P2P user experience by allowing an arbitrary operating channel.
