I know it's just a name, but there is no reason to put "linux" in the
member name. It's the real device phandle value from OpenFirmware not
something invented by Linux's OF layer.
PowerPC uses this for something different, it records the information
here using the special "linux,phandle" and "ibm,phandle" properties.
