    This is a big irq cleanup patch.
    * Use set_irq_chip() to register irq_chip.
    * Initialize .mask, .unmask, .mask_ack field.  Functions for these
      method are already exist in most case.
    * Do not initialize .startup, .shutdown, .enable, .disable fields if
      default routines provided by irq_chip_set_defaults() were suitable.
    * Remove redundant irq_desc initializations.
    * Remove unnecessary local_irq_save/local_irq_restore, spin_lock.
    With this cleanup, it would be easy to switch to slightly lightwait
    irq flow handlers (handle_level_irq(), etc.) instead of __do_IRQ().
    Though whole this patch is quite large, changes in each irq_chip are
    not quite simple.  Please review and test on your platform.  Thanks.
