trace_filter_parse() allocs memory for *out and when
-ENOMEM is returned, caller function, dfsentry_trace_filter_write()
trying to freed this memory.
After this patch, the memory is freed in trace_filter_parse()

The power values coming from the Energy Model are already in uW.
The PowerCap and DTPM frameworks operate on uW, so all places should
just use the values from the EM.
Fix the code by removing all of the conversion to uW still present in it.

cpufreq_driver->fast_switch() callback expects a frequency as a return

amd_pstate_update_freq(), which only indicates a success or failure.
