print_wiki: fix columns calculations

For
- chipsets
- boards, and
- chips

Previously the chipset columns were not uniformly divided at all,
which led to very odd table bottoms. This patches fixes this as far
as wiki code can do (browser rendering can still create odd effects
because we do not define cell heights).

Corresponding to flashrom svn r1556.
