Jan Viktorin 13a1317d3b pci: create device list and fallback on its members 
Now that rte_device is available, drivers can start using its members
(numa, name) as well as link themselves into another rte_device list.

As of now no one is using this list, but can be used for moving over all
devices (pdev/vdev/Xdev) and perform bulk actions (like cleanup).
