Subject: [PATCH 5/4] devfreq: exynos: make some code internal to exynos_ppmu.c
* make exynos_ppmu_[reset,setevent,start,stop,read]() static
* move defines from exynos_ppmu.h to exynos_ppmu.c
* remove unused PPMU_[FLAG,CCNT_OVERFLOW] and [RD,WR]_DATA_COUNT defines
There should be no functional changes caused by this patch.
