Cover letter [PATCH 00/14] cpufreq: create & use cpufreq_generic_init() routine

Many CPUFreq drivers for SMP system (where all cores share same clock lines), do similar stuff in their ->init() part.

This patch creates a generic routine in cpufreq core which can be used by these so that we can remove some redundant code. And later part of patchset makes other drivers use this infrastructure.

Many drivers which weren't setting policy->cpus haven't been updated as they might have separate clocks for CPUs and setting all CPUs in policy->cpus may corrupt them..

This is Sixth part of my cleanup work for CPUFreq, first five are (And obviously its rebased over them):

1: cpufreq: Introduce cpufreq_table_validate_and_show()
https://lkml.org/lkml/2013/8/8/263

2: cpufreq: define generic routines for cpufreq drivers
https://lkml.org/lkml/2013/8/10/48

3. CPUFreq: Implement light weight ->target(): for 3.13
https://lkml.org/lkml/2013/8/13/349

4. CPUFreq: set policy->cur in cpufreq core instead of drivers
https://lkml.org/lkml/2013/8/14/288

5. CPUFreq: Move freq change notifications out of drivers
https://lkml.org/lkml/2013/8/15/506
