genirq: Add state field to irq_data
Some chip implementations need to access certain status flags. With sparse irqs that requires a lookup of the irq descriptor. Add a state field which contains such flags. Name it in a way which will make coders happy to access it with the proper accessor functions. And it's easy to grep for. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
