mac80211: change MIMO_PS to SM_PS

This patch follows 11n spec naming more rigorously replacing MIMO_PS
with SM_PS (Spatial Multiplexing Power Save).

(Originally submitted as 4 patches, "mac80211: change MIMO_PS to SM_PS",
"iwlwifi: change MIMO_PS to SM_PS", "ath9k: change MIMO_PS to SM_PS",
and "iwlwifi: remove double definition of SM PS". -- JWL)
