If CONFIG_OF is not defined, the following error will happen.

This is due to some hidden headers path from linux/of.h to plat/irqs.h
already reported by Russell for prm4xxx.c.

I have the following commit from mainline.  I suspect you have an old

Note: for the next merge window, I'm removing the asm/irq.h include from
asm/prom.h so that this kind of thing doesn't happen in the future.

    Fix by explicitly including it.
