tee: add AMD-TEE driver
Adds AMD-TEE driver.
* targets AMD APUs which has AMD Secure Processor with software-based
Trusted Execution Environment (TEE) support
* registers with TEE subsystem
* defines tee_driver_ops function callbacks
* kernel allocated memory is used as shared memory between normal
world and secure world.
* acts as REE (Rich Execution Environment) communication agent, which
uses the services of AMD Secure Processor driver to submit commands
for processing in TEE environment
