We sometimes see COMMAND_IGNORED responses during the clock stop sequence. It turns out we already have information if devices are present on a link, so we should only prepare those when they are attached. In addition, even when COMMAND_IGNORED are received, we should still proceed with the clock stop. The device will not be prepared but that's not a problem. The only case where the clock stop will fail is if the Cadence IP reports an error (including a timeout), or if the devices throw a COMMAND_FAILED response.
