Exynos cpufreq drivers does not support device tree based regulator lookup, so it can get the VDD ARM regulator only by its name. To get cpufreq working for now, this patch works this around by renaming the regulator in board dts files to vdd_arm, which is the name expected by the driver. This fixes a regression introduced by dropping support of board file based bootup of Exynos 4210 boards that rendered cpufreq inoperable on Trats and Origen boards.
