This patch set introduces a generic TEE subsystem. The TEE subsystem will
contain drivers for various TEE implementations. A TEE (Trusted Execution
Environment) is a trusted OS running in some secure environment, for
example, TrustZone on ARM CPUs, or a separate secure co-processor etc.

Previous RPK releases have provided OP-TEE feature, running on HiSilicon
HiKey board. It's used by LHG and LMG. It's the continuation of the
effort that has been done before, to keep OP-TEE up-to-date with latest
RPK.
