Subject: [PATCH 27/31] cpufreq: sc520: Covert to light weight ->target() routine

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.
