Subject: irqchip/gic-v4: Add forward definition of struct irq_domain_ops
Patch-mainline: v4.15-rc1
Git-commit: 47f9d0bf526058b3fdc077698fcb19748d5700e4
References: FATE#323954

In some randconfig scenarios, including arm-gic-v4.h results
in a spurious wawrning about the $SUBJECT structure not being
defined. Adding a forward definition keeps it quiet.
