Add UCLASS_TEE for Trusted Execution Environment
Adds a uclass to interface with a TEE (Trusted Execution Environment).
A TEE driver is a driver that interfaces with a trusted OS running in
some secure environment, for example, TrustZone on ARM cpus, or a
separate secure co-processor etc.
The TEE subsystem can serve a TEE driver for a Global Platform compliant
TEE, but it's not limited to only Global Platform TEEs.
The over all design is based on the TEE subsystem in the Linux kernel,
tailored for U-Boot.
