This patch reworks the cell iic interrupt handling so that: - Node ID is back in the interrupt number (only one IRQ host is created for all nodes). This allows interrupts from sources on another node to be routed non-locally. This will allow possibly one day to fix maxcpus=1 or 2 and still get interrupts from devices on BE 1. (A bit more fixing is needed for that) and it will allow us to implement actual affinity control of external interrupts. - Added handling of the IO exceptions interrupts (badly named, but I re-used the name initially used by STI). Those are the interrupts exposed by IIC_ISR and IIC_IRR, such as the IOC translation exception, performance monitor, etc... Those get their special numbers in the IRQ number space and are internally implemented as a cascade on unit 0xe, class 1 of each node.
