   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.

pci_bus 0000:01: root bus resource [mem 0xfffffffff4800000-0xfffffffff4ffffff] (bus address [0xf4800000-0xf4ffffff])
pci_bus 0000:01: root bus resource [??? 0x00000001 flags 0x0]
