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.
