Current master: dts/src/arm/socfpga_cyclone5_de0_sockit.dts

Seems I got confused with all the names. So, the dts is called
socfpga_cyclone5_de0_sockit.dts and the model name is "Terasic DE-0(Atlas)"
and Terasic calls it "DE0-Nano-SoC Kit/Atlas-SoC Kit".

I think it should then be

	model = "Terasic DE0-Nano-SoC Kit/Atlas-SoC Kit";

I didn't insist on that when I reviewed the dts for linux, maybe I should
have.
