Subject: [PATCH v2 3/6] ARM: dts: exynos: Fix charging regulator voltage and current for i9100

Set CHARGER current and CHARGER_CV voltage according to Galaxy S2 vendor
sources [0,1].

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

This seems to depend on driver changes, so it will have to wait till
they reach mainline.
