This patch adds the support for loongson2 thermal sensor controller,
which can support maximum 4 sensors.
It's based on thermal of framework:
- Trip points defined in device tree.
- Cpufreq as cooling device registered in loongson2 cpufreq driver.
- Pwm fan as cooling device registered in hwmon pwm-fan driver.

warnings. Either this should be squashed with last patch (driver change)
or just be a last patch in the series.

sorry,I misunderstood the meaning of the tag and didn't intentionally
discard it, I will add "Reviewed-by: Krzysztof Kozlowski
<krzysztof.kozlowski@linaro.org>" on this patch " dt-bindings: thermal:
add loongson2k thermal binding".
