Load the firmware to QUP SE based on the "qcom,load-firmware" property
specified in devicetree. Populate Serial engine and base address details
in the probe function of the protocol driver and pass to firmware load
routine.
Skip the firmware loading if the firmware is already loaded in Serial
Engine's firmware memory area.

I supposed the qupv3fw.elf is SoC specific, so it should use /lib/firmware/qcom
base path and also a SoC/platform specific path that should be specified
with firmware-name in DT.
With this property, "qcom,load-firmware" could be dropped.
