cfg80211/nl80211: support GTK rekey offload
In certain circumstances, like WoWLAN scenarios,
devices may implement (partial) GTK rekeying on
the device to avoid waking up the host for it.
In order to successfully go through GTK rekeying,
the KEK, KCK and the replay counter are required.
Add API to let the supplicant hand the parameters
to the driver which may store it for future GTK
rekey operations.
Note that, of course, if GTK rekeying is done by
the device, the EAP frame must not be passed up
to userspace, instead a rekey event needs to be
sent to let userspace update its replay counter.
