Samsung soc drivers changes for v5.5

Browse source 
1. Minor fixes to Exynos Chipid driver.
 2. Add Exynos Adaptive Supply Voltage driver allowing to adjust voltages
    used during CPU frequency scaling based on revision of SoC.  This
    also pulls dependency from PM/OPP tree - driver uses newly added
    dev_pm_opp_adjust_voltage() function.
