Log message:
It turns out PCI IOC3 card which embed both the Ethernet controller and the
superio chip interrupt on two different pins (yet do not advertize
themselves as a multi-function device, of course).
So, on one hand, this makes the ioc attachment code simpler, because it
simply needs to map interrupt pins A and B, and another hand, this moves
all the interrupt knowledge to the PCI bridge driver, since routing of pin
B differs whether the device is the onboard IOC3 chip (and able to use
any of the 8 bridge interrupt sources...) or on a PCI board (with pin
mapping sane, since controlled by the bridge).
This makes superio interrupts on CADduo boards work. Tested to cause
no regressions on Origin 200, Octane and Fuel.
