ich_descriptors: Add function to guess chipset version
Add guess_ich_chipset() that takes fields from a descriptor dump and
returns the lowest possible chipset version.
Intel did several incompatible changes to the descriptor through the
years. However, they forgot to add a version number. So we have to
apply some heuristics to detect the chipset version in case of exter-
nal flashing.
