This change defines resources for OP-TEE service drivers to register themselves for being bound to when OP-TEE firmware reports the related service is supported. OP-TEE services are discovered during optee driver probe sequence which mandates optee driver is always probe once bound. Discovery of optee services and binding to related U-Boot drivers is embedded upon configuration switch CONFIG_OPTEE_SERVICE_DISCOVERY.
