6ccce69955 PM / devfreq: Add Exynos5-bus devfreq driver for Exynos5250 
Exynos5-bus device devfreq driver monitors PPMU counters and
adjusts operating frequencies and voltages with OPP. ASV should
be used to provide appropriate voltages as per the speed group
of the SoC rather than using a constant 1.025V.
