[GIT PULL 4/5] Late Samsung driver updates for v4.4

 First of all, sorry for misinforming you. It was not v4.1 which worked, but 3.18 one. I never ran 4.1 on this board, it's my
memory's fault...
 Second, the commit which actually broke 5410 is 8cfc7fdd33080e30b86d21b1a8c9ad0686427ddc ("ARM: EXYNOS: move restart code into pmu
driver"). And we don't have 5410 PMU description in our DT, that's the problem.
