Currently, one or more ath12k_hw is part of a device (ath12k_base) but
in future, it would be part of device group abstraction (ath12k_hw_group),
i.e., when multiple radios (ar) across different devices can be combined
together in a device group (ath12k_hw_group).

In order to facilitate the above transition, introduce helpers such as
ath12k_ab_to_ah() and ath12k_ab_set_ah() to get and set values of ath12k_hw
respectively.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
