I think the property referring to the msi controller should have a fixed
name, such as "msi-parent", to go along with "interrupt-parent".
Similarly, I would suggest using an empty "msi-controller" property
to mark the controller that is capable of serving MSIs. The Linux
implementation doesn't currently require the "interrupt-controller"
property, but I think it's good to stay close to the original interrupt
binding here for consistency.
