Add DT binding documentation for the Sophgo SG2042_EVB_V1.X board [1].

1.x? Is the v1.0 something people can get their hands on, or just the v1.1?
What differences do the boards have that are minimal enough that specific compatibles would not be required?

Please run "make CHECK_DTBS=y W=1 your_dtb_file" before submitting patch. I have a quick check and get following warnings/errors:

Error: ....../arch/riscv/boot/dts/sophgo/sg2042-evb-v1.dts:67.1-7 Label or path gmac0 not found
Error: ....../arch/riscv/boot/dts/sophgo/sg2042-evb-v1.dts:86.14-15 syntax error

And the similar issues existing for sg2042-evb-v2.dts.

This should be dropped, we can add this after ethernet support is upstreamed.

The same for evb_v2.

Add DT binding documentation for the Sophgo SG2042_EVB_V1.X board [1].

1.x? Is the v1.0 something people can get their hands on, or just the v1.1?
What differences do the boards have that are minimal enough that specific compatibles would not be required?

First of all, v1.1 and v1.0 are compatible boards. There is no difference between v1.1 and v1.0 from dts.

Both v1.1 and v1.0 have been discontinued.
About 80 pieces of v1.1 are in the hands of community developers.

Add DT binding documentation for the Sophgo SG2042_EVB_V2.0 board [1].
