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.
