* ADC GAIN/DC offset calibration is for calibrating two ADCs that

* 5GHz modes.
*
* It hasn't been confirmed whether doing this calibration is needed
* at all in the above modes and/or whether it's actually harmful.
* So for now, let's leave it enabled and just remember to get
* confirmation that it needs to be clarified.
