Thanks!  For most level type irq chips (which initialize .ack, .mask
and .mask_ack rountine with same function), it should be easy to
migrate to new irq flow handler:

1. replace set_irq_chip() with set_irq_chip_and_handler(..., handle_level_irq)
2. use generic_handle_irq() instead of __do_IRQ()

I'm still not sure for per-cpu type irq chips and egdg type irq chips,
especially i8259.  The i8259 seems not suitable for handle_edge_irq or
handle_level_irq yet.  The irq handling on SMP seems another maze ...
