This obviously only works if the environment variable name can be mapped
to the device node, which isn't always the case. Think of "_" vs "-".
But for simple things like ethaddr, this will work.

We probably shouldn't support undocumented syntax (bindings).

If we only support a predefined list of variables, we can make them
device tree compatible anyway. E.g. we could have a mapping
"serial-number" <-> "serial#"
