+ ath9k_hw: remove ANI function restrictions for AP mode
+
+ The primary purpose of this piece of code was to selectively disable
+ OFDM weak signal detection. The checks for this are elsewhere, and an
+ earlier commit relaxed the restrictions for older chips, which are more
+ sensitive to interference.
