Various wiki output improvements as per IRC discussion

 - Use '?3' wiki template (light greenish, not gray) for untested stuff.
 
 - Reduce page width a bit to improve readability on smaller screens.
 
 - Generalize some functions a bit (pass in how many columns to generate).
 
 - Mark untested board-enables as such (were incorrectly marked "OK" so far).
 
 - Drop some useless 'valign=top' entries.
 
 - Make a few more functions 'static' while we're at it.

Corresponding to flashrom svn r1009.
