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.
Adjust all the dtc test-cases to conform to this rule.

The dtbs_equal_ordered test program is used to implement a number of
testcases. However, the test program itself has never been
particularly well tested. In addition there are testcases coming in
future for which it would be useful to have a corresponding
"dtbs_equal_unordered" which checks for equality of device trees, not
considering the internal ordering of elements. Finally, for some
tests we may want it would be useful to check trees for equality with
the PASS case being when they are *not* equal.
This patch addresses all of the above. A dtbs_equal_unordered is
added, and both it and the existing dtbs_equal_ordered program now
take a -n option to make the PASS case be where the trees are not
equal. A number of example trees with slight modifications from
test_tree1 are used to verify that both these programs correctly
identify when the tree is altered, and a dtb_reverse program is used
to verify that the unordered version does not depend on internal
ordering. These new testcases for the equality testing programs are
split out into a new test group in run_tests.sh.
dtbs_equal_unordered uses the new property iteration functions, and so
this also acts as further testing for those functions.
dtbs_equal_unordered will be useful for further testing the recently
added tree-merging code and its upcoming extensions.
