Samsung fixes for v4.2

Browse Source 
From Krzysztof Kozlowski:
 1. Fix exynos3250 MIPI DSI display and MIPI CSIS-2 camera sensorx
    after adding support for PMU regmap in exynos-video-mipi driver
    (issue introduced in v4.0).
 2. Bring back cpufreq for exynos4210 after incomplete switch to
    cpufreq-dt driver in 4.2 merge window. The necessary DT changes
    for exynos4210 cpufreq was not applied to the same tree as rest
    of patchset because of multiple conflicts between clk and arm-soc
    trees. Unfortunately without the change the exynos4210 boards
    loose cpufreq feature.
