[PATCH 1/9] drivers/of: Make device tree code work on any arch.

[Stephen Neuendorffer]

I'm not sure what the right way to abstract these functions is.
of_node_to_nid seems specific to those platforms which have a root
device tree.  pci_address_to_pio seems to probably have a useful
implementation, but I'm not sure what it's trying to do.  Perhaps
someone can shed some light?
