Hi Petr

I'm not sure this is the correct order. I would actually put NVMEM
after mac-address and local-mac-address. These are well established
and used. We don't want to break existing boards with a new
property. By putting NVMEM later, in order to make it used, any
existing mac-address and local-mac-address need to be removed, making
the developers actually think about what they are doing.
