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'.
