mac80211: add sta_notify_ps callback
This patch is necessary in order to provide a proper Access point support for p54.
Unfortunately for us, there is no documented way to disable the interfering
power save buffering mechanism in firmware completely.
Therefore we give in and notify the driver through our new sta_notify_ps callback,
so that we can update the filter state.
