cpufreq: drivers with target_index() must set freq_table

Browse Source 
Since the cpufreq core directly uses freq_table, for cpufreq drivers
that set their target_index() callback, make it mandatory for them to
set the same.

Since this is set per policy and normally from policy->init(), do this
from cpufreq_table_validate_and_sort() which gets called right after
->init().
