powerpc/pci: move pci_64.c device tree scanning code into pci-common.c
The PCI device tree scanning code in pci_64.c is some useful functionality.
It allows PCI devices to be described in the device tree instead of being
probed for, which in turn allows pci devices to use all of the device tree
facilities to describe complex PCI bus architectures like GPIO and IRQ
routing (perhaps not a common situation for desktop or server systems,
but useful for embedded systems with on-board PCI devices).
This patch moves the device tree scanning into pci-common.c so it is
available for 32-bit powerpc machines too.
