wifi: ath12k: fix ar->supports_6ghz usage during hw register
In the ath12k_mac_hw_register() function's context, ar is an iterator
variable, and there is no assurance that the last ar will be the one with
6 GHz enabled. Therefore, checking directly ar->supports_6ghz outside the
loop is not appropriate.
Additionally, 6 GHz lacks HT capabilities. To obtain the super set of
HT capabilities across all grouped radios, 6 GHz should be excluded.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
