mac80211: add vif debugfs driver callbacks
Add debugfs driver callbacks so drivers can add debugfs entries for interfaces. Note that they _must_ remove the entries again as add/remove in the driver doesn't correspond to add/remove in debugfs; the former is up/down while the latter is netdev create/destroy.
