Fix broken dm_test_ofnode_phandle_ot test. They never actually worked
and were passing test by pure luck by having the same phandle index of
test.dts that coincicentally had #gpio-cells in the same index node.

It was sufficient to add a phandle to test.dts to make the test fail.

To correctly test these feature, make use oif the new OPs oftree to
parse phandle.

For consistency with the dm_test_ofnode_phandle, rework the test and
other.dts to use the same property with the other- prefix to every
node.
