Thomas Monjalon 2f6fec5390 vdev: remove eal prefix
The VDEV code will move to the bus drivers directory.
Rename functions from rte_eal_vdev_ to rte_vdev_
to prepare the move of the driver out of EAL.

The prefix rte_eal_vdrv_ is also renamed to rte_vdev_.
It was used for registration of vdev drivers.
