mainboard/supermicro/h8qme_fam10: Provide local pnp_ sio func

Provide local superio pnp_ programming entry/exit functions as to avoid
    making superio implementation global symbols. Although this is not the
    proper/final solution, it does mitigate possibly symbol collisions and
    allow for continued superio refactorisation.
