SuperI/O detection now happens unconditionally and before the chipset enable
We could run it after chipset enable, but it definitely has to happen
before board enable because the board enable usually accesses the
SuperI/O. With this patch, it is possible to add a struct superio to the
board enable table for more accurate matching in case subsystem IDs are
ambiguous. This patch focuses on the generic infrastructure aspect and
on support for IT8712F/IT8716F.
Thanks go to Adrian Glaubitz and Ward Vandewege for testing.
Corresponding to flashrom svn r813.
