psa: driver wrapper: Change cipher_*_setup signatures

Change the signature of
psa_driver_wrapper_cipher_encrypt/decrypt_setup to
that of a PSA driver cipher_encrypt/decrypt_setup
entry point.

Change the operation context to the PSA one to be
able to call the software implementation from
the driver wrapper later on.
