Add a comment from my local HAL about what is actually going on here
with these ADC DC Gain/Offset calibrations.
The whole idea is to calibrate a pair of ADCs to compensate for any
differences between them.
The AR5416 returns lots of garbage, so there's no need to do the
calibration there.
The AR9160 returns 0 for secondary ADCs when calibrating 2.4ghz 20mhz
modes. It returns valid data for the secondary ADCs when calibrating
2.4ghz HT/40 and any 5ghz mode.
