From: Saravanakumar Duraisamy <quic_saradura@quicinc.com>

Add ath12k_hw_params for the ath12k AHB-based WiFi 7 device IPQ5424.
The WiFi device IPQ5424 is similar to IPQ5332. Most of the hardware
parameters like hw_ops, wmi_init, ring_mask, etc., are the same between
IPQ5424 and IPQ5332, hence use these same parameters for IPQ5424.
Some parameters are specific to IPQ5424; initially set these to
0 or NULL, and populate them in subsequent patches.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01243-QCAHKSWPL_SILICONZ-1
Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.6-01275-QCAHKSWPL_SILICONZ-1
Tested-on: IPQ5424 hw1.0 AHB WLAN.WBE.1.6-01275-QCAHKSWPL_SILICONZ-1
