Subject: [PATCH v3 3/3] ARM: dts: add suspend opp to exynos4412

Mark 800MHz OPP as a suspend opp for Exynos4412 based
boards so effectively cpufreq-dt driver behavior w.r.t.
suspend frequency matches what the old exynos-cpufreq
driver has been doing.

This patch fixes suspend/resume support on Exynos4412 based
Trats2 board and reboot hang on Exynos4412 based Odroid U3
board.
