[PATCH v4 4/5] ethdev: add notifications for probing and removal

[Thomas Monjalon <thomas@monjalon.net>]

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.
