This patch adds support for new flash which indicates that trip point triggers irq when temperature is met. Exynos5433 supports 8 trip point which will trigger irq. Above that number other trip points should be registered without 'irq-mode' flag. That will force the thermal framework to start polling the temperature sensor under configured conditions and handle the trip point.
