C and other Super I/O cosmetic fixes.
- Random coding style, whitespace and cosmetic fixes.
- Consistently use the same spacing and 4-hexdigit port number format
in the pnp_dev_info[] arrays.
- Drop dead/unused code and less useful comments.
- Add missing "(C)" characters and copyright years.
- Shorten and simplify some code snippets.
- Use u8/u16/etc. everywhere.
