  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.
