From: Karthikeyan Periyasamy <quic_periyasa@xxxxxxxxxxx>
Currently MAC HW un/register helper function support the single radio.
To enable single/multi link operation in the future, the following helper
functions need to be refactored to accommodate multiple radios under a
single MAC HW un/register:
* ath12k_ah_to_ar()
* ath12k_mac_hw_allocate()
* ath12k_mac_hw_register()
* ath12k_mac_hw_unregister()
This refactoring will make it easier to scale these functionalities and
support Multi link operation.
