This application requires PSA, so enable the PSA feature for all
targets. We do this so we can run this application on targets that don't
have PSA enabled by default, leaving it up to applications to turn on
the feature if desired.
We'll enable the PSA feature on targets in Mbed OS instead. That way, the regression tests can verify that the target has PSA integrated 100% correctly.
