powerpc/64: Move pci_device_from_OF_node() out of asm/pci-bridge.h 

Move pci_device_from_OF_node() in pci64.c because it needs definition
of struct device_node and is not worth inlining.

ppc32.c already has it in pci32.c.

That way pci-bridge.h doesn't need linux/of.h (Brought by asm/prom.h
via asm/pci.h)
