Staging: winbond: mac80211 - unify config_interface and bss_info_changed

The commit 'mac80211: unify config_interface and bss_info_changed' from
Johannes Berg <johannes@sipsolutions.net> removed the config_interface structure
tag from struct ieee80211_ops. The BSSID detection functionality migrated to
ieee80211_ops.bss_info_changed.

Since wbsoft_config_interface() was largely empty, there wasn't much to do
other then to remove the function itself. There is currently no support
for BSSID change detection.
