[RFC PATCH v2 3/3] drivers: mfd: Add support for Exynos PMU driver

This patch moves Exynos PMU driver implementation from
"arm/mach-exynos" to "drivers/mfd".
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 DT based
implementation of PMU driver.
This driver uses already existing DT binding information.
