The RTL8231 is an external chip, and not part of the SoC. That means it is more appropriate to define it in the board specific (base) files, instead of the DT include for the SoC itself. Moving the RTL8231 definition also ensures that boards with no GPIO expander, or an alternative one, don't have a useless gpio1 node label defined. Tested on a Netgear GS110TPPv1.
