Doesn't look like anyone has near-term plans for upstreaming non-OPTEE
TEEs, we don't at least (TI), so I guess I see no reason right now to
delay upstreaming of this TEE's driver on the off-chance it is
incompatible with a TEE that may or may not try to get upstreamed later.
I'll redact my objection for now.
