genirq: Add preflow handler support
sparc64 needs to call a preflow handler on certain interrupts befor calling the action chain. Integrate it into handle_fasteoi_irq. Must be enabled via CONFIG_IRQ_FASTEOI_PREFLOW. No impact when disabled. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: David S. Miller <davem@davemloft.net>
