From: Balamurugan S <quic_bselvara@quicinc.com>

Current ath12k devices, QCN9274 and WCN7850, supports m3.bin firmware
download through ath12k driver. The new ath12k AHB based device
IPQ5332 supports m3 firmware download through remoteproc driver.

Hence, add new parameter (fw.m3_loader) in ath12k_hw_params to avoid
m3 firmware download in IPQ5332.

Tested-on: IPQ5332 hw1.0 AHB WLAN.WBE.1.3.1-00130-QCAHKSWPL_SILICONZ-1
Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.1.1-00210-QCAHKSWPL_SILICONZ-1
