Add support for generic power domain for Exynos4 platforms and remove the Samsung specific power domain control for Exynos4. The generic power domain infrastructure is used to control the power domains available on Exynos4. For non-dt platforms, the power domains are statically instantiated. For dt platforms, the power domain nodes found in the device tree are instantiated.
