This is "incorrect" in respect to the standard DT translation of
"ranges" property. And applies for PCIe. Anyway, it works correctly just
because mvebu PCIe drivers (both u-boot and linux) have workarounds for
those issues, and expects that DT are "incorrect". So lets say mvebu
PCIe defined _new DT standard_ for PCIe incompatible with DT standard.
