[ Upstream commitfa17ff8e32] In order to get working interrupts, a low offset value needs to be configured. The minimum value for it is 20 Celsius, which is what is configured when there's no lower thermal trip (ie the thermal core passes -INT_MAX as low trip temperature). However, when the temperature gets that low and fluctuates around that value it causes an interrupt storm. Prevent that interrupt storm by not enabling the low offset interrupt if the low threshold is the minimum one.
