wifi: ath12k: refactor ath12k_mac_allocate() and ath12k_mac_destroy()
Currently, the MAC allocation and destroy helper functions are tightly
coupled with the link/radio (ar) structure. In the future, to support
single/Multi link operations, need to refactor these helper functions
across the core and mac sub modules, so that it can be easy to scale
these functions to support single/Multi link operations.
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
