The irq_domain_add() function needs the number of interrupts in the

The number of interrupts will depend on the OMAP generation. That one is
just valid for the 3430 INTC controller.
Since the previous code was using zero, I guess that using 0 there
should be fine.
Moreover, that piece of code should not exist anymore on 3.3 if the
series I sent last month to leverage Rob's DT interrupt init is merged [1].
I've just ping Rob and Grant on that series to get a status.

Benoit
