How am I supposed to override this in the board dtb when my board only
uses 1 slave?

Should I then be setting this to disabled from my board file? Or does
the disabled for the ethernet overall take care of that?

I guess the board file would have to disable that too (we won't have a
phy given we are connecting to a switch chip).
