We have a strict separation between enum TpmModel and tpm_models[]:
* TpmModel may have any number of members. It just happens to have one.
* tpm_register_model() uses the first empty slot in tpm_models[].
If you register more than tpm_models[] has space,
tpn_register_model() fails. Its caller silently ignores the
failure.
Register the same TpmModel more than once has no effect other than
wasting tpm_models[] slots: tpm_model_is_registered() is happy with
the first one it finds.
Since we only ever register one model, and tpm_models[] has space for
just that one, this contraption even works.
Turn tpm_models[] into a straight map from enum TpmType to bool. Much
simpler.
