intel_pstate: Remove energy reporting from pstate_sample tracepoint

intel_pstate: Remove energy reporting from pstate_sample tracepoint

Remove the reporting of energy since it does not provide any useful
information about the state of the driver and will be a maintainance
headache going forward since the RAPL energy units register is not
architectural and subject to change between micro-architectures
