The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have been kept around for migration reasons. After more than two years it's time to remove them finally. This patch cleans up one of the remaining users. When all such patches hit mainline we can remove the defines and typedefs finally. Impact: cleanup Convert the last remaining users to struct irq_chip and remove the define.
