[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <festevam@denx.de>

While bringinp up a new board without the MAC fuses programmed,
the following error message was observed:

Error: ethernet@30bf0000 address not set.

Improve the error message to make it clearer the reason of
the failure.
