Create a mechanism for looking up a device_t associated with an ofw/fdt
xref handle, and for registering that association.  Also use the same data
for faster translations between node and xref handles.

Now when fdt properties contain &othernode references, a driver can find
the device instance that corresponds to &othernode, and thus can use
interfaces provided by that instance.
