ARM: dts: qcom: use min temp TSENS for thermal VDD restriction for LITO

Use min temp TSENS thermal zone of each TSENS controller instead of
individual TSENS for cold temperature VDD restriction rules for LITO.
It avoids interrupt storm at cold temperature due to interrupt
from each individual TSENS for VDD restriction.
