mac80211: enable spatial multiplexing powersave
Enable spatial multiplexing in mac80211 by telling the
driver what to do and, where necessary, sending action
frames to the AP to update the requested SMPS mode.
Also includes a trivial implementation for hwsim that
just logs the requested mode.
For now, the userspace interface is in debugfs only,
and let you toggle the requested mode at any time.
