PM: EM: Extend em_cpufreq_update_efficiencies() argument list 

In order to prepare the code for the modifiable EM perf_state table,
make em_cpufreq_update_efficiencies() take a pointer to the EM table
as its second argument and modify it to use that new argument instead
of the 'table' member of dev->em_pd.

No functional impact.
