Ronald Cron 2091eed609 psa: driver: Reduce the scope of test driver entry points
Define test driver entry points that provide an alternative
to Mbed TLS driver entry points only when the PSA configuration
is used. Their purpose is only to test the PSA configuration
thus there is no good reason to use them out of this scope.
