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.
