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.
forgot to set the IORESOURCE_BUS bus flag which led to incorrect resource
assignments and a non-working stifb framebuffer on most parisc machines.
LBA 10:1: PCI host bridge to bus 0000:01
pci_bus 0000:01: root bus resource [io 0x12000-0x13fff] (bus address [0x2000-0x3fff])
pci_bus 0000:01: root bus resource [mem 0xfffffffffa000000-0xfffffffffbffffff] (bus address [0xfa000000-0xfbffffff])
pci_bus 0000:01: root bus resource [mem 0xfffffffff4800000-0xfffffffff4ffffff] (bus address [0xf4800000-0xf4ffffff])
pci_bus 0000:01: root bus resource [??? 0x00000001 flags 0x0]
