[PATCH v3 4/5] PCI: xgene-msi: Include <linux/irqdomain.h> explicitly

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>

pci-xgene-msi.c uses irq_domain_add_linear() and related interfaces, so it
needs <linux/irqdomain.h> but doesn't include it directly; it relies on the
fact that <linux/of_irq.h> includes it.

But pci-xgene-msi.c *doesn't* need <linux/of_irq.h> itself.  Include
<linux/irqdomain.h> directly to remove this implicit dependency so a future
patch can drop <linux/of_irq.h>.
