+ ath9k_hw: reduce ANI spur immunity setting on HT40 extension channel
+
+ The cycpwr_thr1 value needs to be lower on the extension channel than on
+ the control channel, similar to how the register settings are programmed
+ in the initvals.
+
+ Also drop the unnecessary check for HT40 - this register can always be
+ written. This patch has been reported to improve HT40 stability and
+ throughput in some environments.
