Register the device node so we can actually make use of the cells from
within the device tree.

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#"
