Support Engicam MicroGEA-MX6UL SoM with:

 - 256 Mbytes NAND Flash
 - 512 Mbytes DRAM DDR2
 - Ethernet MAC

Signed-off-by: Dario Binacchi <dario.binacchi@amarulasolutions.com>

---

Changes in v2:
- Change local-mac-address to 00 00 00 00 00 00. The actual value will
  be set by the bootloader. The previous one was assigned to Freescale
  Semiconductor.

Not related this patch, latest device tree binding for nand-controler should
look like

	nand@0 {
		reg = <0>;
		nand-ecc-mode = "hw";
		...
	}

I am not sure if above dts work at your ul board.

I tested the change you suggested, but it's not working on my board.

I also did a search through various DTS files on the i.MX6ULL SOM, and indeed,
the scheme I adopted is used by other boards that have already been merged.

Thanks and regards,
Dario
