Add support for TEE based trusted keys where TEE provides the functionality
to seal and unseal trusted keys using hardware unique key. Also, this is
an alternative in case platform doesn't possess a TPM device.

This patch-set has been tested with OP-TEE based early TA which is already
merged in upstream [1].

Is the new RPI400 computer a platform that can be used for testing
patch sets like this? I've been looking for a while something ARM64
based with similar convenience as Intel NUC's, and on the surface
this new RPI product looks great for kernel testing purposes.

Here [1] is the list of supported versions of Raspberry Pi in OP-TEE.
The easiest approach would be to pick up a supported version or else
do an OP-TEE port for an unsupported one (which should involve minimal
effort).

If porting is doable, then I'll just order RPI 400, and test with QEMU
up until either I port OP-TEE myself or someone else does it.

For seldom ARM testing, RPI 400 is really convenient device with its
boxed form factor.
