[PATCH 09/11] DT: arm: exynos: add support for thermal trip irq-mode

[Lukasz Luba]

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.
