PCI: Use preserve_config in place of pci_flags
Use preserve_config in place of checking for PCI_PROBE_ONLY flag to enable support for "linux,pci-probe-only" on a per host bridge basis. This also obviates the use of adding PCI_REASSIGN_ALL_BUS flag if !PCI_PROBE_ONLY, as pci_assign_unassigned_root_bus_resources() takes care of reassigning the resources that are not already claimed.
