Asymmetric crypto algorithms such as SM2, EdDSA would need per op
capability and based on it, the input param to a crypto operation
is chosen wisely.

v3:
- Removed unused rte_crypto_sm2_op_capa enum value RTE_CRYPTO_SM2_PKE_KDF.
HW that needs it can add this enum.
- Test and driver changes split from it and follows within same series.
