Tim Harvey a2f5e9a6f2 PCI: dwc: Do not remap invalid res
[ Upstream commit 6e5ebc96ec651b67131f816d7e3bf286c635e749 ]

On imx6 and perhaps others when pcie probes you get a:
imx6q-pcie 33800000.pcie: invalid resource

This occurs because the atu is not specified in the DT and as such it
should not be remapped.
