Stephen Warren c9d9121683 Warn on node name unit-address presence/absence mismatch 
ePAPR 1.1 section 2.2.1.1 "Node Name Requirements" specifies that any
node that has a reg property must include a unit address in its name
with value matching the first entry in its reg property. Conversely, if
a node does not have a reg property, the node name must not include a
unit address. Also allow ranges property as it is deemed valid, but ePAPR
is not clear about it.

Implement a check for this. The code doesn't validate the format of the
unit address; ePAPR implies this may vary from (containing bus) binding
to binding, so doing so would be much more complex.

README 

The source tree contains the Device Tree Compiler (dtc) toolchain for
working with device tree source and binary files and also libfdt, a
utility library for reading and manipulating the binary format.

DTC and LIBFDT are maintained by:

David Gibson <david@gibson.dropbear.id.au>
Jon Loeliger <jdl@jdl.com>
