wifi: ath12k: support 2 channels for single pdev device

Browse source 
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.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
