thermal/drivers/mediatek/lvts: Disable low offset IRQ for minimum threshold
[ Upstream commit fa17ff8e325a657c84be1083f06e54ee7eea82e4 ]
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.
