[RFC][PATCH] cpufreq: Support of Energy Performance preference

[Srinivas Pandruvada]

This change allows user to provide hints to P-State selection algorithm
to be more more performance centric or more energy centric.

Even if this change only impacts intel_pstate driver, this change is
submitted as RFC to check if we need a generic method in cpufreq to
support such configuration.

If other SoCs don't allow such configuration, then this change can be only
in intel_pstate using local cpufreq attributes as it is implemented now.
