GENI QUP firmware loading is normally expected to be completed by a
previous boot stage and is not required in production U-Boot builds.
Add CONFIG_QCOM_GENI_FW_LOAD to make the late firmware loading path
optional and disable it by default.
The option can be enabled for engineering and bring-up builds where
loading GENI firmware from U-Boot is required.
This feature is enabled by default on Linux, why would it be disabled
by default on U-Boot ?
