Refrain from defining default fw_cfg register offsets on unsupported architectures -- throw an error instead. If QEMU were to add fw_cfg support on additional architectures, we should add them to the FW_CFG_SYSFS depends statement in drivers/firmware/Kconfig, and provide default values for register offsets in drivers/firmware/qemu_fw_cfg.c at that time.
