[PATCH V2 28/35] cpufreq: s3c64xx: Covert to light weight ->target_index() routine

[Viresh Kumar <viresh.kumar@linaro.org>]

This patch converts existing .target() to newly defined light weight
.target_index() routine for this driver.

CPUFreq core will call cpufreq_frequency_table_target() before calling this
routine and will pass index to it.
