mac80211: introduce beacon-only timing data
In order to be able to predict the next DTIM TBTT in the driver, add the ability to use timing data from beacons only with the new hardware flag IEEE80211_HW_TIMING_BEACON_ONLY and the BSS info value sync_dtim_count which is only valid if the timing data came from a beacon. The data can only come from a beacon, and if no beacon was received before association it is updated later together with the DTIM count notification.
