powerpc/pci: Use common PHB resource hookup
The 32-bit and 64-bit powerpc PCI code used to set up the resource pointers of the root bus of a given PHB in completely different places. This unifies this in large part, by making 32-bit use a routine very similar to what 64-bit does when initially scanning the PCI busses. The actual setup of the PHB resources itself is then moved to a common function in pci-common.c. This should cause no functional change on 64-bit. On 32-bit, the effect is that the PHB resources are going to be setup a bit earlier, instead of being setup from pcibios_fixup_bus().
