ARM: dts: socfpga: Add support of Terasic DE0 Atlas board

The Terasic DE0 Atlas board is also known as the DE0-Nano board.
This patch adds the DTS board file for the DE0-Nano Sockit board, and not
the DE0 Nano "Development Board".

v3: Updated skew settings for the gmac1 node as this board is using the
    KSZ9031 PHY instead of the 9021 PHY.
v2: use stdpath-out for console and remove comment regarding u-boot ethaddr
