ARM: dts: exynos: Mark 1 GHz CPU OPP as suspend OPP on Exynos5250

commit 645b23da upstream.

1 GHz CPU OPP is the default boot value for the Exynos5250 SOC, so mark it
as suspend OPP. This fixes suspend/resume on Samsung Exynos5250 Snow
Chomebook, which was broken since switching to generic cpufreq-dt driver
in v4.3.
