ath9k: fix regression which disabled ps on ath9k

Browse source 
The patch titled "ath9k: Add new file init.c" shuffled some code
around but in dong so for some reason also removed the revision
check for disablign power save. Add this revision check again
so we can get power save re-enabled again by default on cards
newer than AR5416 and AR5418.

$ git describe --contains 556242049c
v2.6.34-rc1~233^2~49^2~343

This patch has fixes for stable kernels [2.6.34+].
