Subject: [PATCH v2 10/11] arm: dts: exynos5422: add support for thermal trip
 irq-mode

This patch adds support for new flag which indicates
that trip point triggers IRQ when temperature is met.
Exynos5422 supports 4 trip points which will trigger IRQ.
Additional trip points should be registered without 'irq-mode' flag.
