[dpdk-dev] [PATCH v5 04/15] crypto/mlx5: add basic operations

[Shiri Kuzin]

The basic dev control operations are configure, close and get info.

Extended the existing support of configure and close:
        -mlx5_crypto_dev_configure- function used to configure device.
        -mlx5_crypto_dev_close-  function used to close a configured
         device.

Added config struct to user private data with the fields socket id,
number of queue pairs and feature flags to be disabled.
