Note that this symbol cannot be selected by the user, only indirectly
via the MDIO_BUS_MUX_GPIO symbol (in patch 3/3) which has the proper
dependencies.
If we were to specify the dependencies in both places, we gain nothing other than duplication of information.
However, if you insist, I will of course add it here too.
