X86 cannot store the irq domain pointer in struct device without breaking
XEN because the irq domain pointer takes precedence over arch_*_msi_irqs()

To achieve this XEN MSI interrupt management needs to be wrapped into an
irq domain.

Move the x86_msi ops setup into a single function to prepare for this.
