[PATCH] irqchip/gic-v2m: fix missing include of <linux/irqchip/arm-gic.h>

Fix the missing declaration of gicv2m_init() by including the
file <linux/irqchip/arm-gic.h> which defines it. Fixes the
warning:

drivers/irqchip/irq-gic-v2m.c:517:12: warning: symbol 'gicv2m_init' was not declared. Should it be static?
