  853a33ce6932 irqchip: gic-v2m: Add support for ARM GICv2m MSI(-X) doorbell

Introduced a series of warnings when building ARM multi_v7_defconfig:

  include/linux/irqchip/arm-gic.h:109:53: warning: its scope is only this definition or declaration, which is probably not what you want
  In file included from arch/arm/mach-ux500/pm.c:13:0:
  include/linux/irqchip/arm-gic.h:109:53: warning: 'struct irq_domain' declared inside parameter list
   int gicv2m_of_init(struct device_node *node, struct irq_domain *parent);
                                                       ^

Fix this by adding the proper include.

I've added this to irqchip/irqdomain-arm locally and pushed it to next.  If
there are no objections, I'll push it to irqchip/irqdomain-arm.

thx,

Jason.
