sparc/PCI: convert to pci_create_root_bus()
Convert from pci_create_bus() to pci_create_root_bus(). This way the root
bus resources are correct immediately. This patch doesn't fix a problem
because sparc fixed the resources before scanning the bus, but it makes
sparc more consistent with other architectures.
v2: fix build error (from sfr)
