From: Rob Herring <robh@xxxxxxxxxx>
Using non-translatable addresses in platform device names is wrong
because they may not be globally unique. Just use the default naming with
a global index if the address cannot be translated instead.
of_can_translate_address has the same checks as of_translate_address, so
we can remove it here as well.
