[PATCH 5/9] wifi: ath12k: Refactor radio frequency information

[Kalle Valo]

From: Karthikeyan Periyasamy <quic_periyasa at quicinc.com>

Currently, radio stores the low frequency and high frequency information as
separate variables. However, cfg80211 already provides a suitable data
structure struct wiphy_radio_freq_range to store this information efficiently.
Additionally, for multi radio per wiphy infrastructure, this frequency range
information is essential. In future patches using struct wiphy_radio_freq_range
makes the code simpler.

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
