I assumed that I forgot that piece during backporting but infact it was
not part of the original patch.

One side note: Since we need to specify IRQCHIP_EOI_THREADED and
handle_fasteoi_late_irq() as the handler, would it be easily doable to use
the handle_fasteoi_irq() handler and skip the EOI in the threaded mode?
But if it creates a mess then leave it as it is.
