[PATCH V2 12/35] cpufreq: elanfreq: Covert to light weight ->target_index() routine

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.
