The helper API, rte_cryptodev_vdev_pmd_init(), has a parameter of
struct rte_vdev_device *, which needs to include rte_vdev.h.
We will move vdev into drivers/bus, so we need to avoid such
dependency. And also, we cannot break the ABI.
This patch changes that pointer to void *, and defines an internal
structure same with struct rte_vdev_device.
