mac80211: clean up beacon interval settings
We currently have two beacon interval configuration knobs: hw.conf.beacon_int and vif.bss_info.beacon_int. This is rather confusing, even though the former is used when we beacon ourselves and the latter when we are associated to an AP. This just deprecates the hw.conf.beacon_int setting in favour of always using vif.bss_info.beacon_int. Since it touches all the beaconing IBSS code anyway, we can also add support for the cfg80211 IBSS beacon interval configuration easily. NOTE: The hw.conf.beacon_int setting is retained for now due to drivers still using it -- I couldn't untangle all drivers, some are updated in this patch.
