In previous codes, the bridge is owned by hypervsior if there is pre-launched VM configured. This can cause bug, e.g. the net card behind the bridge cannot get IP because the write to bridge's command register to set BusMaster bit is ignored. This patch is to refine the codes to make the bridge be managed by Service VM if the device behind the bridge is not assigned to pre-launched VM. Furthermore, it adds the parent device into struct pci_pdev to construct PCI hierarchy. Tracked-On: #8849 Signed-off-by: Yi Sun <yi.y.sun@intel.com>
