PowerCap: Add class driver

The power capping framework providing a consistent interface between the
kernel and user space that allows power capping drivers to expose their
settings to user space in a uniform way.
The overall design of the framework is described in the documentation
added by the previous patch in this series.

+          The power capping sysfs interface allows kernel subsystems to expose power
+          capping settings to user space in a consistent way.  Usually, it consists
+          of multiple control types that determine which settings may be exposed and
+          power zones representing parts of the system that can be subject to power
+          capping.
