genirq: Export dummy_irq_chip

Export dummy_irq_chip to modules to allow them to do things such as

	irq_set_chip_and_handler(virq,
				 &dummy_irq_chip,
				 handle_level_irq);
This fixes

	ERROR: "dummy_irq_chip" [drivers/gpio/gpio-pcf857x.ko] undefined!

when gpio-pcf857x.c is being built as a module.
