arm: socfpga: socrates: Add eth0 alias to enable ethernet
This enables full ethernet usage, including U-Boot to write the board specific MAC address (ethaddr) into the DT blob before passing it to Linux. Without this, the ethaddr is not detected in U-Boot at all, resulting in this error upon bootup: ... Model: EBV SOCrates Net: Error: ethernet@ff702000 address not set. No ethernet found.
