Disable big.LITTLE switcher in order to allow automatic usage of
cpufreq-dt driver on Exynos542x/Exynos5800 SoCs based boards.

This change should not cause any problems as arm_big_little[_dt]
driver (which is using big.LITTLE switcher support to do the "real"
big.LITTLE switching work) is not used on any Exynos SoC based
board currently.

I agree. I pushed out my queue and I do not plan to push 3rd round so
this will wait till v4.8.
