[U-Boot] [PATCH 3/5] net: sandbox: Convert sandbox mock eth driver to livetree

[Joe Hershberger]

Use the dev_ functions to access DT properties.

Also correct the reading of the fake MAC address. The format from the DT
is u32s, so to accurately read the MAC from the DT, we need to cast each
value to a u8.
