wifi: nl80211: Documentation update for NL80211_CMD_PORT_AUTHORIZED event

Drivers supporting 4-way handshake offload for AP/P2p-GO and
STA/P2P-client should use this event to indicate that port has
been authorized and open for regular data traffic, sending
this event on completion of successful 4-way handshake.
