nl80211: advertise GTK rekey support, new triggers
Since we now have the necessary API in place to support GTK rekeying, applications will need to know whether it is supported by a device. Add a pseudo-trigger that is used only to advertise that capability. Also, add some new triggers that match what iwlagn devices can do.
