[PATCH] ARM: OMAP2+: Fix prm2xxx_3xxx.c INT_34XX_PRCM_MPU_IRQ build error

[Cousson, Benoit]

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

arch/arm/mach-omap2/prm2xxx_3xxx.c:41:11: error:
 ?INT_34XX_PRCM_MPU_IRQ? undeclared here (not in a function)

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

Add the #include <plat/irqs.h> in prm2xxx_3xxx.c to avoid depending
of that hidden dependency that should probably not exist in theory.

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

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.

    a missing include for plat/irqs.h:

OK, it was part of the fixes Tony sent for for v3.3-rc2 but that are 
were not in mainline until now.
I've just pulled -rc3 and this is indeed there.

Thanks,
