Add support for the Terasic DE0-Nano/Atlas-SoC Kit, which is a CycloneV based board. The board can boot from SD/MMC. Ethernet is a bit different because it has a KSZ9031 PHY, so for now, ethernet doesn't quite work yet, as a few patches are needed to support the PHY.
I thought we did support the KSZ9031 PHY. What's the problem ?

Hi Marek,
This patch is based on your u-boot-socfpga/wip/boards branch.
OK, that makes sense.
Thanks, Dinh

I think it might be clearer to rename it to de0-nano-soc, what do you think ? What's the difference between de0-nano-soc and atlas btw ?

I think you don't need the DM_SEQ_ALIAS, it's needed only for QSPI to enforce the SPI NOR ordering.
