ath6kl: make sure WLAN power save is enabled during suspend

Browse source 
Power save is enabled during ath6kl init. But when user space disables power
save, the system will go into suspend with power save disabled. The ath6kl
driver will now explicitly enable power save prior to entering suspend and
restore its previous setting upon resume
