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.
