basic_mmio_gpio would need to use iomap for this and a lot of platforms
don't support generic iomap - so no it won't.
You don't generally want want to create sub platform devices anyway
without care as it makes sysfs, pci removal and power management ugly and
takes up *more* memory than repeating the code in the first places.
