mainboard/google/reef: add pen connections

A pen interface was added. Prepare for possibly testing it by
    plumbing in the gpio configuration. It's very possible these
    changes need to be tweaked, but no driver code has been seen
    yet nor a datasheet detailing how some of these signals actually
    function.
