Not neccessary anyway, after talking Jason C in a Kirkwood-only
workaround I prepared a patch that reads mac address registers early
and stores it in the local-mac-address property.

Just tested on Dockstar with gated clocks and modular DT mv643xx_eth.

Will append to the DT mv643xx_eth patch set if a v5 will be required
or as single patch prior Jason C taking in the ARM part of it
otherwise.
