[PATCH 154/228] cpufreq: davinci: Convert to light weight ->target_index() routine

[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.
