[dpdk-dev] [PATCH v4 7/8] cryptodev: update fast path APIs to use new flat array

[Akhil Goyal <gakhil@marvell.com>]

Rework fast-path cryptodev functions to use rte_crypto_fp_ops[].
While it is an API/ABI breakage, this change is intended to be
transparent for both users (no changes in user app is required) and
PMD developers (no changes in PMD is required).
