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.

                         Current Multi wiphy Model
