ARM: dts: Add suspend configuration for max77686 regulators for exynos4412-trats2
Add suspend to RAM configuration for max77686 regulators. Some LDOs and bucks are disabled. This reduces energy consumption during S2R, approximately from 17 mA to 9 mA. Additionally remove old and not supported bindings: - regulator-mem-off - regulator-mem-idle - regulator-mem-on The max77686 driver does not parse them and they are not documented anywere.
