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.

Changes since v2:
- Release allocated shared memory from bind_service_drivers() only.
- Remove definition of useless macro OPTEE_SERVICE_DRIVER_GET().
Changes since v1:
- Remove all #ifdef CONFIG_OPTEE_SERVICE_DISCOVERY directives and replace
with if (IS_ENABLED()) where applicable.
- Incidentally rename local function open_session() to open_enum_session()
and remove local function close_session() for clarity.
- Update commit log to highlight that "optee driver is always probe once
bound" when CONFIG_OPTEE_SERVICE_DISCOVERY is enable.
