of the old API.

* The IRQ bitmap provides a global map of bound IRQ vectors for a
* given platform. Allocation of IRQs are either static through the CPU
* vector map, or dynamic in the case of board mux vectors or MSI.
*
* As this is a central point for all IRQ controllers on the system,
* each of the available sources are mapped out here. This combined with
* sparseirq makes it quite trivial to keep the vector map tightly packed
* when dynamically creating IRQs, as well as tying in to otherwise
* unused irq_desc positions in the sparse array.
