[PATCH] [CPUFREQ] EXYNOS: Use static for functions used in only this file

[Tushar Behera <tushar.behera@linaro.org>]

Fixes following sparse error.
drivers/cpufreq/exynos-cpufreq.c:34:5: warning: symbol
'exynos_verify_speed' was not declared. Should it be static?
drivers/cpufreq/exynos-cpufreq.c:40:14: warning: symbol
'exynos_getspeed' was not declared. Should it be static?
