Commit 762792913f8c (PM / OPP: Fix get sharing CPUs when hotplug
is used) moved away from using cpu_dev->of_node because of some
limitations.
However, commit 7467c9d95989 (of: return of_get_cpu_node from
of_cpu_device_node_get if CPUs are not registered) added support to
fall back to of_get_cpu_node() if called if CPUs are not registered
yet.
Add the missing of_node_put() for the CPU device nodes. Also go back
to using of_cpu_device_node_get() in dev_pm_opp_of_get_sharing_cpus()
to avoid scanning the device tree again.

The for_each_available_child_of_node() loop in _of_add_opp_table_v2()
doesn't drop the reference to "np" on errors. Fix that.

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.
