[RFC PATCH 1/2] drivers: mfd: Add support of exynos-pmu driver

[Pankaj Dubey <pankaj.dubey@samsung.com>]

From: Younggun Jang <yg1004.jang@samsung.com>

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.
