Bryan Wu says of creating the platform_device in the leds driver:

So I did. Currently I don't know of any reliable way to detect the
hardware platform, the device that's listening on the LED GPIO
I/O ports isn't on the PCI bus and there is no ACPI support on this
system, so I can't see anything to do except unconditionally create
the platform_device.
