wifi: ath12k: Refactor core startup 



In the upcoming hardware device group abstraction 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() are part of
ath12k_core_start() and ath12k_core_pdev_create() respectively and are based on
per device (struct ath12k_base). These APIs can be decoupled and moved out to
ath12k_core_qmi_firmware_ready() itself. This refactor is helpful for device
group abstraction when mac80211 allocate and register will be changed from per
device (struct ath12k_base) to per device group (struct ath12k_hw_group).

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
