Adrian Chadd aacc74998a Fix 5ghz calibration logic when using AR9280 w/ fast clock.
When the fast clock (44mhz) is enabled for 5ghz HT20, the
dual ADCs aren't enabled. Trying to do the ADC calibrations
here would result in calibration never completing; this
resulted in IQ calibration never running and thus performance
issues in 11a/11n HT20 mode.

Leave it enabled for non-fastclock (40mhz) 11a mode and
HT40 modes.

This has been fixed in discussion with Felix Fietkau (nbd)
and discussions with the Atheros baseband team.

Linux ath9k now has a similar fix.
