Subject: [PATCH 07/11] DT: arm64: exynos7: add support for thermal trip irq-mode

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.

Exynos7?

Beside that comments from previous email apply (no need to duplicate them).

Best regards,
