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.

This implements a generic interface towards a Trusted Execution

Environment (TEE). A TEE is a trusted OS running in some secure
