The reason is that platform_devices are for stuff that fundamentally cannot
be probed but has to be hardcoded in some place.
The point about the of device tree is that it allows you to probe this
kind of device. This means you get automatic module loading based on the
device tree, and that the devices show up in sane locations in /sys.
