psa: cipher: Fix symmetric key management

Browse Source 
Symmetric key management is not intended to be
delegated to drivers. Thus, key management code
for a given symmetric key type should be included
in the library whether or not the support for
cryptographic operations based on that type of
symmetric key may be delegated to drivers.
