X86 cannot store the irq domain pointer in struct device without breaking XEN because the irq domain pointer takes precedence over arch_*_msi_irqs() fallbacks. XENs MSI teardown relies on default_teardown_msi_irqs() which invokes arch_teardown_msi_irq(). default_teardown_msi_irqs() is a trivial iterator over the msi entries associated to a device. Implement this loop in xen_teardown_msi_irqs() to prepare for removal of the fallbacks for X86. This is a preparatory step to wrap XEN MSI alloc/free into a irq domain which in turn allows to store the irq domain pointer in struct device and to use the irq domain functions directly.
