I guess you could append it to the name (eg, "SMCCC TRNG ${UUID}")
though it'd be a bit of an eyesore if anyone displays that in UIs much?

A separate version string queryable in parallel with name would be more
work but possibly a bit more sensible, some other hardware entropy
sources will have firmware version numbers or similar they could
usefully report I expect.
