Add vdev functions so they can be reused by both partition mode and sharing mode code: pci_find_vdev_by_vbdf: search for vdev by virtual bdf pci_find_vdev_by_pbdf: search for vdev by physical bdf Tracked-On: #2534 Signed-off-by: dongshen <dongsheng.x.zhang@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
