arm: add set_handle_irq() to register the parent IRQ controller handler function
In order to allow irqchip drivers to register their IRQ handling function as the parent IRQ controller handler function, we provide a convenience function. This will avoid poking directly into the global handle_arch_irq variable. Suggested by Arnd Bergmann.
