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.
