sparc64: Propagate PCI device archdata into OF device tree for EBUS.
In order to convert EBUS drivers doing DMA into pure OF drivers, we need the of_device->dev.archdata setup properly. EBUS instances that can provide DMA for device nodes sit on PCI, so detect and propagate the information there. Signed-off-by: David S. Miller <davem@davemloft.net>
