[dpdk-dev] [PATCH v10 4/7] ethdev: make get port by name and get name by port public

[Reshma Pattan <reshma.pattan@intel.com>]

Converted rte_eth_dev_get_port_by_name to a public API.
Converted rte_eth_dev_get_name_by_port to a public API.
Updated the release notes with the changes.

The librte_pdump library provides the APIs to enable or disable the
packet capture either using the port id or pci address or device name.
So pdump library need to do a mapping from name to port and port to name
internally to validate the device name and register the Rx and Tx
callbacks for the mapped ports. So these APIs are made public for the
pdump library for doing the mentioned mappings.
