[PATCH 4/9] wifi: ath12k: introduce interface combination cleanup helper

[Kalle Valo]

From: Karthikeyan Periyasamy <quic_periyasa at quicinc.com>

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

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
