util/superiotool: distinguish between VT82C686 and VT1211
They both have a device id of 0x3c. The former is part of the PCI chip set
accessible via port 0x3f0 while the latter is a standalone LPC chip accessible
via 0x2e/0x4e depending on strapping.
They're not register compatible: the VT82C686 only provides a FDC, LPT and part
of UARTs.
The VT82C686 documentation suggests it has revision 0x00 while the VT1211
datasheet indicates 0x01. Nevertheless, the VT1211 I happen to have hs a
revision of 0x02. Thus the revision is probably not good enough to tell one
from the another.
