With the introduction of hierarchy irqdomain, struct irq_data becomes per-chip instead of per-irq and there may be multiple irq_datas associated with the same irq. Some per-irq data stored in struct irq_data now may get duplicated into multiple irq_datas, and causes inconsistent view. So introduce struct irq_common_data to host per-irq common data and to achieve consistent view among irq_chips. Signed-off-by:
