From: Hanjun Guo <hanjun.guo@linaro.org> commit d59f6617eef0 (genirq: Allow fwnode to carry name information only) forgot to do "domain->fwnode = fwnode;" for irqchips being probed via ACPI namesapce (DSDT/SSDT), that will break platforms with irqchip such as mbigen or qcom irq combiner, set the fwnode back to fix the issue.
