This interface should only be used when a device other than the bridge
handles PCI interrupts on the PCI bus. The initiating device is specified
with a PCI device number, and the pin represents PCI interrupt lines
(A, B, C, or D) as numbers in the range of 0 to 3.

int device, int pin);

int device, int pin);
