Viresh Kumar	009acd196f	PM / OPP: Support updating performance state of device's power domain The genpd framework now provides an API to request device's power domain to update its performance state. Use that interface from the OPP core for devices whose power domains support performance states. Note that this commit doesn't add any mechanism by which performance states are made available to the OPP core. That would be done by a later commit. Note that the current implementation is restricted to the case where the device doesn't have separate regulators for itself. We shouldn't over engineer the code before we have real use case for them. We can always come back and add more code to support such cases later on.

PM / OPP: Support updating performance state of device's power domain

The genpd framework now provides an API to request device's power
domain to update its performance state.  Use that interface from the
OPP core for devices whose power domains support performance states.

Note that this commit doesn't add any mechanism by which performance
states are made available to the OPP core. That would be done by a
later commit.

Note that the current implementation is restricted to the case where
the device doesn't have separate regulators for itself. We shouldn't
over engineer the code before we have real use case for them. We can
always come back and add more code to support such cases later on.

Use snprintf() to avoid unnecessary initializations, avoid calling
kfree().

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.
