[PATCH 1/3] wifi: ath12k: Introduce iface combination cleanup helper

[Karthikeyan Periyasamy <quic_periyasa@xxxxxxxxxxx>]

Introduce a cleanup helper function to avoid redundant code for iface
combination cleanup. Remove the cleanup code from
ath12k_mac_hw_unregister() and ath12k_mac_hw_register() and replace it
with new cleanup helper function.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00188-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00183-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1
