ARM: tegra: ouya: Enable memory frequency thermal throttling using ACTMON 



The ACTMON module monitors activity of memory clients and then devfreq
driver makes decisions about a required memory frequency based on info
from ACTMON. Add ACTMON device to the thermal zone of Ouya in order to
use it as a cooling device which throttles memory freq on overheat.
