mb/google/nissa/var/uldren: Add FW_CONFIG probe for fivr
Uldren will support internal fivr in next phase and using fw_config to decide the board with internal or external fivr. BUG=b:287379760 BRANCH=firmware-nissa-15217.B TEST=boot to ChromeOS, cold reboot/suspend/recovery mode/install OS work normally.
