i2c: s3c2410: dont need CPU_FREQ transitions for exynos series
For Exynos4 and Exynos5 SoCs from Samsung the i2c clock is based on a fixed 66 MHz peripheral clock, and therefore is completely independent of the cpu frequency. Thus, registering for a CPU freq notifier is very wasteful. This patch modifes the code such that, i2c bus registers to cpu_freq_transition only if CONFIG_CPU_FREQ_S3C24XX is enabled. This change should save a bunch of cpufreq transitions calls which does not apply to exynos SoCs.
