Change pm_runtime_forbid to pm_runtime_disable to disable RPM on
platforms that don't support runtime D3, as re-enabling it through sysfs
auto power control may cause the controller to malfunction. This can lead
to issues such as hotplug devices not being detected due to failed
interrupt generation.
