[V3,7/9] cpufreq: maple: Use 'index' only to index into policy->freq_table

Later patches would make changes in cpufreq core, after which
policy->freq_table may be reordered by cpufreq core and it wouldn't be
safe anymore to use 'index' for any other local arrays.

To prepare for that, use policy->freq_table[index].driver_data for other
driver specific usage of 'index'. The 'driver_data' fields are already
set properly by the driver.
