tee: add tee_shm_register_{user,kernel}_buf()
Adds the two new functions tee_shm_register_user_buf() and
tee_shm_register_kernel_buf() which should be used instead of the old
tee_shm_register().
This avoids having the caller supplying the flags parameter which
exposes a bit more than desired of the internals of the TEE subsystem.
