From: Karthikeyan Periyasamy <quic_periyasa@xxxxxxxxxxx>
Hardware device group abstraction would be introduced, in future,
where radios across different devices can be grouped together to
support multi-link operation and register as a device group to mac80211.
Currently, ath12k_mac_allocate() and ath12k_mac_register() APIs are part
of ath12k_core_start() and ath12k_core_pdev_create() respectively and are
based on per device (ath12k_base). These APIs can be decoupled and moved
out to ath12k_core_qmi_firmware_ready() itself.
This refactor would be helpful for device group abstraction when mac80211
allocate and register will be changed from per device (ath12k_base) to
per device group (ath12k_hw_group).
Add changes to move allocate and register APIs from existing one and modify
corresponding deinit sequence.
