of/platform: fix device naming for non-translatable addresses
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.
