sh: intc: Implement reverse mapping for IRQs to per-controller IDs.
This implements a scheme roughly analogous to the PowerPC virtual to hardware IRQ mapping, which we use for IRQ to per-controller ID mapping. This makes it possible for drivers to use the IDs directly for lookup instead of hardcoding the vector. The main motivation for this work is as a building block for dynamically allocating virtual IRQs for demuxing INTC events sharing a single INTEVT in addition to a common masking source.
