PCI: xgene: Request host bridge window resources
Request host bridge window resources so they appear in ioport_resource and
iomem_resource and are reflected in /proc/ioports and /proc/iomem.
For example, the following entries did not previously appear in /proc/iomem:
e180000000-e1ffffffff : /soc/pcie@1f2b0000
e180000000-e182ffffff : PCI Bus 0000:01
e180000000-e181ffffff : 0000:01:00.0
e182000000-e1820fffff : 0000:01:00.0
e182100000-e1821fffff : 0000:01:00.0
f000000000-ffffffffff : /soc/pcie@1f2b0000
