HACK: iommu: apple-dart: workaround broken runtime PM with PCIe devices
Runtime PM behaves strangely with PCIe devices, pm_runtime_enabled() returns true here although the devices do not support runtime PM. This seems to confuse the PM core and DART is runtime suspended while the device is in use. The dart_hw_reset() in the resume path ends up breaking PCIe devices eventually.
