mac80211: add basic support for WoWLAN
This adds basic support for the new WoWLAN
configuration in mac80211. The behaviour is
completely offloaded to the driver though,
with two new callbacks (suspend/resume).
Options for the driver include a complete
reconfiguration after wakeup, and exposing
all the triggers it wants to support.
