eventdev: make vdev init and uninit functions optional
Made libeventdev library independent of VDEV bus by moving vdev pmd specific function to rte_eventdev_pmd_vdev.h header file. Eventdev VDEV PMD can include that for generic eventdev VDEV init and uninit function enablement. Signed-off-by: Jerin Jacob <jerin.jacob@caviumnetworks.com>
