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.
