From: Thomas Abraham <thomas.ab@xxxxxxxxxxx>
The new CPU clock type allows the use of generic arm_big_little_dt
cpufreq driver for Exynos5420.
Changes by Bartlomiej:
- split Exynos5420 support from the original patch
- disable cpufreq if big.LITTLE switcher support is enabled
Changes by Ben Gamari:
- rebase
