ath9k_hw: fix parsing of HT40 5 GHz CTLs

commit 904879748d7439a6dabdc6be9aad983e216b027d upstream.

The 5 GHz CTL indexes were not being read for all hardware
devices due to the masking out through the CTL_MODE_M mask
being one bit too short. Without this the calibrated regulatory
maximum values were not being picked up when devices operate
on 5 GHz in HT40 mode. The final output power used for Atheros
devices is the minimum between the calibrated CTL values and
what CRDA provides.
