PCI: of: Ignore resources with failed translation
This patch allows PCI host controller to function even if part of resources is unusable for some reason. An example is non-LPAE kernel on a machine which has some 64-bit resources. Unusable resources will be just skipped instead of a complete failure. Signed-off-by: Pavel Fedin <p.fedin@samsung.com> Signed-off-by: Rob Herring <robh@kernel.org>
