There's currently a comment in the code saying function 0 is GPIO. Instead of hardcoding it, let's add a member where an SoC can specify it. No known SoCs use a number other than 0, but this just makes the code clearer. NOTE: no SoC code needs to be updated since we can rely on zero-initialization.
