ARM: dts: exynos: Expand the voltage range of buck1/3 regulator for exynos4412-odroidu3
This patch expands the voltage range of buck1/3 regulator due to as following: - MIF (Memory Interface) bus frequency needs the range of '900 - 1100 mV'. - INT (Internal) bus frequency needs the range of '900 - 1050 mV'.
