We have a strict separation between enum TpmType and be_drivers[]: * TpmType may have any number of members. It just happens to have one. * tpm_register_driver() uses the first empty slot in be_drivers[]. If you register more than tpm_models[] has space, tpm_register_driver() fails. Its caller silently ignores the failure. If you register more than one with a given TpmType, tpm_display_backend_drivers() will shows all of them, but tpm_driver_find_by_type() and tpm_get_backend_driver() will find only the one one that registered first. Since we only ever register one driver, and be_drivers[] has space for just that one, this contraption even works. Turn be_drivers[] into a straight map from enum TpmType to driver. Much simpler, and has a decent chance to actually work should we ever acquire additional drivers. While there, use qapi_enum_parse() in tpm_get_backend_driver().
