For single pdev device, radio number of a device is forced as 1 in ath12k_wmi_ext_soc_hal_reg_caps_parse(). This leads to ah->num_radio == 1 and then in ath12k_mac_setup_iface_combinations() we report to mac/cfg80211 that only 1 channel is supported. In MLO case, it finally results in failing to bring up the second link as it is in another channel. Change num_different_channels to 2 to allow a second link. Since DFS on multiple channels are not supported yet, remove radar_detect_widths. For now WCN7850 is the only single pdev device, so others should not be affected.
