A few platforms are currently missing clocksource_probe() completely in their time_init functionality. On OMAP3430 for example, this is causing cpuidle to be pretty much dead, as the counter32k is not going to be registered and instead a gptimer is used as a clocksource. This will tick in periodic mode, preventing any deeper idle states. While here, also drop one unnecessary check for populated DT before existing clocksource_probe() call.
