Merge tag 'samsung-soc-4.5' of https://git./linux/kernel/git/krzk/linux into next/soc

Samsung Exynos improvements for 4.5:
1. Switch from Exynos-specific restart/poweroff handler
   (mach-exynos/pmu.c) to generic syscon-reboot and syscon-poweroff
   drivers.
   This depends on adding syscon nodes to DTS to preserve
   bisectability.
2. Minor improvements.
