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.
