We've got most of one for the ARM targets (see hw/arm_pic.h). This file 
contains both the target independent bits and the ARM specific bits for 
emulating the CPU IRQ/FIQ pins.

Annother possibility to abstract this to use a single interrupt line object 
rather than an {object,index} pair. This simplifies code that that raises 
interrupts, at the expense of some complication in the code to create 
interrupt controllers.
