[PATCH v4 03/12] wifi: ath12k: modify ath12k mac start/stop ops for single wiphy

[Rameshkumar Sundaram <quic_ramess@xxxxxxxxxxx>]

From: Sriram R <quic_srirrama@xxxxxxxxxxx>

When mac80211 does drv start/stop, apply the state change
for all the radios within the wiphy in ath12k.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
