The new CPU clock type allows the use of generic CPUfreq drivers. So for Exynos4210/5250, switch to using generic cpufreq driver. For Exynos5420, which did not have CPUfreq driver support, enable the use of generic CPUfreq driver.

While you're at it, can you add this to so we don't have to patch
kernels for the Chromebook2 and Odroid-XU3?
