Eduardo Valentin 616a66351d arm: dts: add cooling properties on omap4460 cpu node
OMAP4460 devices can reach high temperatures and thus
needs to have cpufreq-cooling on systems running on it.

This patch adds the required cooling device properties
so that cpufreq-cpu0 driver loads the cooling device.
