If the device tree node for the bus has a "msi-parent" property, use
that as the default MSI controller for devices on the bus. Add device
tree binding documentation describing the new property.
This allows the pci-host-generic driver to be used in systems with
multiple MSI controllers.

I don't think you need this anymore with 4.3-rc1. The core IRQ subsystem
should take care of parsing and configuring the MSI parents.
I will re-test and see if I can make it work.
