This is a preparation patch for separating the vfio_pci driver to a subsystem driver and a generic pci driver. This patch doesn't change any logic. The new vfio_pci_core_device structure will be the main structure of the core driver and later on vfio_pci_device structure will be the main structure of the generic vfio_pci driver.
