[dpdk-dev] [PATCH] ethdev: add notifications for probing and removal

When a PMD finishes probing, it creates the new port by calling
the function rte_eth_dev_allocate().
A notification of the new port is sent there to the upper layer.
When a PMD finishes removal of a port, it calls the function
rte_eth_dev_release_port().
A notification of the destroyed port is sent there to the upper layer.

This patch depends on:
- ethdev: remove useless parameter in callback process
- ethdev: free a port by a dedicated API
