Need not a new reset binding for sg2000, you can reuse existing
sophgo,sg2042-reset.yaml.

Use your contact info if really need this file.
In fact, I think your patch can be combined with another patch [1].
Because SG2000/SG2002 are actually developed from CV18XX, their reset IP
is almost the same.

Can you talk with Inochi on this?

I think use sophgo,cv1800b-reset is enough, there should be no difference
between them.
