I had a report that Xen fails to boot with this series and !CONFIG_TEE.
This is because you return an error here in all the case some domain
creation will always fail.
Instead this should check that tee_type is always NONE or else return an
error.
Also, please at least check that your series does not break boot when
CONFIG_TEE is not selected. It would also be ideal (but not mandatory)
if you can check that it does not break on non-OPTEE platform when
!CONFIG_TEE is selected.
Cheers,
