As suggested by Eduardo Valentin this adds the thermal zone for the bcm2835 SoC with its single thermal sensor. We start with the criticial trip point and leave the cooling devices empty since we don't have any at the moment. Since the coefficients could vary depending on the SoC we need to define them separate.
