Felix Fietkau 3ff25093cb ath9k_hw: fix duplicate (and partially wrong) definition of AR_CH0_THERM
AR_PHY_65NM_CH0_THERM and AR_CH0_THERM were supposed to refer to the
same register, however they had different SREV checks.

Remove the duplicate and use the checks. Since there were other SREV
checks present in the only place that uses this, this will probaby not
affect runtime behavior.

Sujith Manoharan 6fcbe538be ath9k: Fix issue with MCS15
On some boards which are based on AR9300, AR9580 or
AR9550, MCS15 usage is problematic.

This is because these boards use a "frequency doubler",
which doubles the refclk to get better EVM, but causes
spurs. Handle this properly in the driver to recover
throughput.

Rajkumar Manoharan 0b6eb36622 ath9k_hw: Fix wrong peak detector DC offset
An issue is reported in AR9462 & AR9565 that NF_cal_not_done is
not observed when HW peak detector calibration is disabled. At that
state, the HW is stuck at NF calibration which prevents tx output.
The root cause is wrong peak detector offset calibrated by HW. To
resolve this issue, peak detector calibration is done manually by SW
for AR9462 and AR9565.
