This device_type is bogus.  Remember having a valid device_type is the
exception not the rule.  Really the only common device_type values are
"cpu", "memory", "network" and "serial".

I know you said this is still needed, but the driver really needs to
be fixed.  This is not a proper way of using the device tree for
logical numbering.
