dm: core: Enable optional use of fdt_translate_address()
The current "simple" address translation simple_bus_translate() is not
working on some platforms (e.g. MVEBU). As here more complex "ranges"
properties are used in many nodes (multiple tuples etc). This patch
enables the optional use of the common fdt_translate_address() function
which handles this translation correctly.
