    kconfig: tristate choices with mixed tristate and boolean values
    
    Change kconfig behavior so that mixing bool and tristate config settings in
    a choice is possible and has the desired effect of offering just the
    tristate options individually if the choice gets set to M, and a normal
    boolean selection if the choice gets set to Y.
