Subject: [PATCH 11/12] ARM: dts: exynos: remove unneeded DVS voltages from PMIC on Arndale

The S5M8767 PMIC does not require anymore a safe DVS voltage, if the DVS
GPIO is not enabled.  Although previously bindings required providing
this safe DVS voltage, but since commit 04f9f068a619 ("regulator:
s5m8767: Modify parsing method of the voltage table of buck2/3/4") this
was ignored.
