wifi: ath12k: Show per-radio center freq in dp stats

Browse Source 
Currently, the frequency on which each radio is operating
is not available in device_dp_stats. This information is
helpful in debugging the channel-specific throughput and
is available with iw/nl80211 dump.

Extend the device_dp_stats dump to display the center
frequency in the existing per-radio loop.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01243-QCAHKSWPL_SILICONZ-1
