Sowmiya Sree Elavalagan 8fb66931fe wifi: ath12k: Enable IPQ5424 WiFi device support
Currently, ath12k AHB (in IPQ5332) uses SCM calls to authenticate the
firmware image to bring up userpd. From IPQ5424 onwards, Q6 firmware can
directly communicate with the Trusted Management Engine - Lite (TME-L),
eliminating the need for SCM calls for userpd bring-up.

Hence, to enable IPQ5424 device support, use qcom_mdt_load_no_init() and
skip the SCM call as Q6 will directly authenticate the userpd firmware.

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
