	  SOCs have a standard set of tuples consisting of frequency and
	  voltage pairs that the device will support per voltage domain. This
	  is called Operating Performance Point or OPP. The actual definitions
	  of OPP varies over silicon within the same family of devices.

	  OPP layer organizes the data internally using device pointers
	  representing individual voltage domains and provides SOC
	  implementations a ready to use framework to manage OPPs.

PM / OPP: Move the OPP directory out of power/ The drivers/base/power/ directory is special and contains code related to power management core like system suspend/resume, hibernation, etc. It was fine to keep the OPP code inside it when we had just one file for it, but it is growing now and already has a directory for itself. Lets move it directly under drivers/ directory, just like cpufreq and cpuidle.
