net/mlx: support firmware version query
The API function rte_eth_dev_fw_version_get() is querying drivers via the operation callback fw_version_get(). The implementation of this operation is added for mlx4 and mlx5. Both functions are copying the same ibverbs field fw_ver which is retrieved when calling ibv_query_device[_ex]() during the port probing. It is tested with command "drvinfo" of examples/ethtool/.
