superio/winbond/w83627hf: Avoid .c includes in mainboards

Move towards the removal of the superio model specific xxx_serial_enable
implementation. Make remaining superio romstage parts link-time symbols
and fix corresponding mainboards to match.

The following mainboards remain unconverted as they are ROMCC:
 - mainboard/supermicro/x6dai_g
 - mainboard/supermicro/x6dhe_g
 - mainboard/supermicro/x6dhr_ig
 - mainboard/supermicro/x6dhr_ig2
and so block the final removal of w83627hf_serial_enable().

Special cases:
 - 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 possible symbol collisions and
allow for continued superio refactorisation.
