This patch moves Exynos PMU driver implementation from "arm/mach-exynos" to "drivers/soc/samsung". This driver is mainly used for setting misc bits of register from PMU IP of Exynos SoC which will be required to configure before Suspend/Resume. Currently all these settings are done in "arch/arm/mach-exynos/pmu.c" but moving ahead for ARM64 based SoC support, there is a need of this PMU driver in driver/* folder. This driver uses existing DT binding information and there should be no functionality change in the supported platforms.
