wifi: ath12k: Enable IPQ5424 WiFi device support

Browse source 
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.
