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.
