From: Pankaj Dubey <pankaj.du...@samsung.com>
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.
