ath6kl: implement ath6kl_cfg80211_suspend()
This is in preparation for cutpower suspend feature. HIF layer makes
the decision based on information provided by cfg80211 and what hardware
actually supports. Then it calls ath6kl_cfg80211_suspend() to enable
the chosen mode.
Functionality should be the same, this is just preparation for
more suspend modes (cutpower and wow).
