       parisc/PCI: lba: convert to pci_create_root_bus() for correct root bus
                        resources
    
      Supply root bus resources to pci_create_root_bus() so they're correct
      immediately.  This fixes the problem of "early" and "header" quirks seeing
      incorrect root bus resources.
    
    added tests for elmmio_space.start while it should use
    elmmio_space.flags.  This for example led to incorrect resource
    assignments and a non-working stifb framebuffer on most parisc machines.
