[PATCH V2 12/35] cpufreq: elanfreq: Covert to light weight ->target_index() routine
From: viresh.kumar@linaro.org (Viresh Kumar)

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.
