Subject[PATCH 11/31] cpufreq: elanfreq: Covert to light weight ->target() routine
Date
This patch converts existing .target_old() to newly defined light weight
.target() routine for this driver.

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