DT just describe the hardware, so if it's a different hardware, they
should have different name.
red0 for GPIO 0, red1 for GPIO 1 or choose other good name instead of 0 and 1.

If this is true, you can just name one LED like gpio-led and let the
kernel to add number after that name. I don't think this is a good
idea to name the hardware. And These aren't like other devices which
will create device node like /dev/video0 /dev/video1. This is from
device tree to describe the hardware.
