Subject: [RFC PATCH 2/5] wifi: ath12k: Add ath12k_hw_params for IPQ5424

From: Saravanakumar Duraisamy <quic_saradura@...cinc.com>

Add ath12k_hw_params for the new ath12k AHB-based WiFi device IPQ5424.
The WiFi device IPQ5424 is similar to IPQ5332. Most of the hardware
parameters like hw_ops, wmi_init, hal_ops, 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: IPQ5424 hw1.0 AHB WLAN.WBE.1.5-01053-QCAHKSWPL_SILICONZ-1
Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.3.1-00130-QCAHKSWPL_SILICONZ-1
