While we'll continue to support barebox,provide-mac-address, new boards
should prefer using the upstream NVMEM binding for describing the MAC address.

Add an example to the documentation.

Do we still need to list it as example? Seems a bit odd for deprecated
bindings.

It's useful to illustrate the difference to the NVMEM binding. Also deprecation
might be a bit harsh. We will likely never remove support, but we'll try
to curtail proliferation.
