exti hardware point of view, there is no specific action on set_affinity.
So the affinity must be forwarded to parent if there is a
descendent irqchips, otherwise just return IRQ_SET_MASK_OK_DONE.

Hi Marc

Just a gentleman ping about this patch.
I verified, you could always apply this patch on linux master branch.
