I noticed that the Merlin NICs I had (AR9220, AR9280) never completed
the ADC calibrations if the NIC is in 5ghz 11a or 5ghz HT/20 modes.
I've been told that the dual-ADC is only engaged in turbo/40mhz modes.

Since Sowl (AR9160) seems to return valid-looking calibration data
in 5ghz 20MHz modes, I'm only disabling it for Merlin for now.
It may turn out I can disable it for all chipsets and only enable
it for 40MHz modes.
