PCI: Make rescan bus could increase bridge resource size if needed

Current rescan will not touch bridge MMIO and IO.

Try to reuse pci_assign_unassigned_bridge_resources(bridge) to update bridge
resource, if child devices need more resource.

only do that for bridges that all children get removed before. So do not
release resources that could already be used by drivers of child devices.
