[PATCH v4] powernv: Dynamic Frequency Scaling Enablement

[Gautham R. Shenoy]

From: "Gautham R. Shenoy" <ego at linux.vnet.ibm.com>

Hi,

This is the v4 of the patchset to enable Dynamic Frequency Scaling
on IBM PowerNV Platforms. I have incorporated the review comments
from the previous version (can be found at [1]). 

In this version, 

  * Multiple patches from the previous version have been into a single
    patch, since the higher numbered patches implemented some helper
    functions and the driver methods which should have been a part of
    the first patch to begin with.

  * Use the generic helpers provided by the cpufreq core available in
    the latest linux-next tree.

  * Fix the code to avoid casting integer pointers to void.

The patch is based on top of the commit:06ed26d1de59ce7cbbe68378b7e470be169750e5
of the linux-next tree.
