It is called only once for single_pdev_only, and then set up all channels for 2G/5G/6G. The logic of ath11k_mac_setup_channels_rates() is not suitable for single_pdev_only, it leads to all 6G channels being disabled for the device interface which is single_pdev_only such as WCN6855. Add channel frequency checks for the 6G band and enable the 6G channels properly based on what is supported by the chip.
