pirq_routing: Allow routing with more than 4 PIRQ links
pirq_routing_irqs assumed that only four links are available for PIRQ routing, INTA to INTD. Some chipsets provide more, up to INTH. When pirq_routing_irqs found a link number greater than 4 in the pirq table, it would not assign that IRQ. This is a shame, as it limits the flexibility of routing IRQs. Make the maximum number of links a Kconfig variable, and modify the code to respect it. This works beatifully on the VX900, which provides 8 routable interrupts. While we're at it, also refactor pirq_routing_irqs, and add some much needed comments. Rename pirq_routing_irqs to pirq_route_irqs to demistify the role of this function. The copyrights added were determined from git log filename.
