Subject[PATCH 16/21] powerpc: Add missing prototype for init_IRQ
A function init_IRQ was added without a prototype declared in header irq.h.
Fix the following warning (treated as error in W=1):

CC arch/powerpc/kernel/irq.o
arch/powerpc/kernel/irq.c:662:13: error: no previous prototype for ‘init_IRQ’ [-Werror=missing-prototypes]
void __init init_IRQ(void)
cc1: all warnings being treated as errors
