Disentangle 3.6/4.0 *_PSA_INIT/DONE variants

Since PSA is always on in 4.x, *_PSA_INIT() and *_PSA_DONE() can be
simply aliased to PSA_INIT() and PSA_DONE() until such a time as we
remove them.

Simplify the login of these PSA_INIT/DONE variants by aliasing them in
4.x and keeping the more complex 3.6 logic entirely separate.
