PCI/MSI: xgene: Remove msi_controller assignment
After 8d63bc7beaee ("PCI/MSI: pci-xgene-msi: Get rid of struct
msi_controller"), it is no longer required to assign msi_controller for
X-Gene PCIe host bridge to support MSI.
Remove this unnecessary code. This also avoids a warning message ("failed
to enable MSI") during boot.
