Subject: [PATCH v4 6/7] ARM: dts: exynos: Fix charging regulator voltage and current for i9100

Set CHARGER current and CHARGER_CV voltage according to Galaxy S2 Epic
4G Touch SPH-D710 Android vendor sources [0,1].

Remove regulator-always-on. The regulator can be enabled and disabled
based on extcon events.
