This is the wrong DT.
What you AFAIK want is the socfgpa_cyclone5_de0_sockit.dts
The "Terasic DE0-Nano" is the same as the "Terasic DE-0" or isn't it?

With the other dts you then should be able to remove

the gpio nodes. The leds phandle should go in the upstream linux DT,
too, so it could be used here. As long as it isn't, this looks okay IMHO.

This looks to be correct in the upstream de0 dts and can also
be removed here.
