Subject: [PATCH] cpufreq: exynos: Get booting freq value in
 exynos_cpufreq_init

commit 6e45eb12fd1c741d556bf264ee98853b5f3104e5 upstream.

Boot_freq is for saving booting freq. But exynos_cpufreq_cpu_init
is called in hotplug. If boot_freq is existed in exynos_cpufreq_cpu_init,
boot_freq could be changed.
