smegw01: Read the second MAC address

Currently, only the first MAC address is read from the fuses.

The second MAC address is not read and Linux assigns a random one.

To prevent this behavior, read the second MAC address from the fuses
and store it into the eth1addr environment variable so that it
can be passed to Linux.
