[PATCH v5 7/9] PCI: xgene: Set msi_controller->dev to platform_device, not pci_bus

[Bjorn Helgaas]

Other users of struct msi_controller set msi->dev to the platform_device of
the PCI host controller, not the device of the pci_bus for the root bus.

Set X-Gene's msi_controller->dev to the PCI host controller platform_device
as other platforms do.
