ARM: dts: exynos: Remove unnecessary address/size properties in Midas boards

The children of regulators node do not have reg/ranges properties.  Move the
children up one level, get rid of regulators node and remove
address-cells and size-cells properties.  This fixes warnings for
Exynos4412 Midas family boards:
