tee: optee: Export OP-TEE message UID check API

Browse Source 
OP-TEE message UID check API can be useful to know whether OP-TEE
is enabled on not assuming the corresponding SMC call is properly
handled if OP-TEE is not supported.

This API can be used by platform code to know OP-TEE presence and
on that basis OP-TEE DT node can be added as part of DT fixups for
the OP-TEE driver probe to happen for both U-Boot and Linux.
