[PATCH 06/40] cryptodev: separate key exchange operation enum

[Arek Kusztal]

- separated key exchange enum.
Key exchange and asymmetric crypto operations like signatures,
encryption/decryption should not share same operation enum as
its use cases are unrelated and mutually exclusive.
Therefore op_type was separate into:
1) operation type
2) key exchange operation type
