If I'm this right it says your regulatory for the card is world
regulatory. This means 5GHz is pretty much locked out - at least for
APs (which initiate radiation, NO-IR flag on all channels).

For comparison, one of my QCA99X0's says:

[ 4450.629243] ath: EEPROM regdomain: 0x0
[ 4450.629248] ath: EEPROM indicates default country code should be used
[ 4450.629250] ath: doing EEPROM country->regdmn map search
[ 4450.629252] ath: country maps to regdmn code: 0x3a
[ 4450.629254] ath: Country alpha2 being used: US
[ 4450.629256] ath: Regpair used: 0x3a

Here's a command snippet from my system for comparison:
