We shouldn't. The reason the patch exists is so that *if* firmware were to
add support for physical PCI/eBus devices in CMO mode in the future, then
we could get into a scenario where there are such devices in the device
tree and we would want to prevent them from getting initialized
on a kernel without the code needed to support such a feature.
