Subject: irqchip/MSI: Use irq_domain_update_bus_token instead of an open coded
 access
Patch-mainline: v4.13-rc1
Git-commit: 96f0d93a487e13233c95397aa3ecaf9cc8ff04bf
References: FATE#323954

Now that we have irq_domain_update_bus_token(), switch everyone over
to it. The debugfs code thanks you for your continued support.
