of_find_device_by_node() may be called by a driver following
of_platform_populate in order to bind the children to drivers.
It's thus wrong to return NULL when a device has been found, but no
driver was registered. That also aligns the function with the
expectation resulting from its name: A device is found and devices may
be bound or not.
