soc: qcom: geni-se: Add support to load QUP SE Firmware via Linux subsystem

In Qualcomm SoCs, firmware loading for Serial Engines (SE) within the QUP
hardware has traditionally been managed by TrustZone (TZ). This restriction
poses a significant challenge for developers, as it limits their ability to
enable various protocols on any of the SEs from the Linux side, reducing
flexibility.

Load the firmware to QUP SE based on the 'firmware-name' property specified
in devicetree at bootup time.
