Subject: [PATCH v4 3/5] driver: soc: exynos-pmu: Add an API to be called after
 wakeup

This patch adds an API exynos_sys_powerup_conf to be called after system sleep
wakeup. This will useful for exynos7 SoC to perform resume related
initialisations. This is similar to currently existing API
exynos_sys_powerdown_conf.
