[PATCH 6/8] cpufreq: qcom-cpufreq-hw: Use auto-registration for energy model

[Viresh Kumar]

Use the CPUFREQ_REGISTER_WITH_EM flag to allow cpufreq core to
automatically register with the energy model.

This allows removal of boiler plate code from the driver and fixes the
unregistration part as well.
