Always configure PSA-based keys for encryption and decryption

Mbed TLS cipher layer allows usage of keys for other purposes
than indicated in the `operation` parameter of `mbedtls_cipher_setkey()`.
The semantics of the PSA Crypto API, in contrast, checks key
usage against the key policy.

As a remedy, this commit modifies the PSA key slot setup to
always allow both encryption and decryption.
