Node name unit-addresses should generally never begin with 0x or leading
0s. Add warnings to check for these cases, but only for nodes without a
known bus type as there should be better bus specific checks of the
unit address in those cases. Any unit addresses that don't follow the
general rule will need to add a new bus type. There aren't any known
ones ATM.

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.

This patch adds an extra testcase to dtc to ensure that the
"reg_format" and "ranges_format" checks trigger as they should if a
'reg' or 'ranges' property appears in the root node.
