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

 * relevant for 2.4GHz 20MHz wide modes because, as far as I can tell,
 * the secondary ADC is never enabled. It is enabled however for
 * 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.

 * See US Patent No: US 7,541,952 B1:
