I applied but basically, we have to avoid using hard coded value like 64 on
this. The NR_IRQS depends on CPU not board but this change is needed for
supporting some specific board and if you need more interrupt numbers, will
you increase it? It is not good way.

We need to fix this up next time.

Thanks.
