PM: EM: Implement em_nl_get_pd_table_doit()
When a userspace requests EM_CMD_GET_PD_TABLE with an ID of a performance
domain, the kernel reports back the energy model table of the specified
performance domain. The message format of the response is as follows:
EM_A_PD_TABLE_PD_ID (NLA_U32)
EM_A_PD_TABLE_PS (NLA_NESTED)*
EM_A_PS_PERFORMANCE (NLA_U64)
EM_A_PS_FREQUENCY (NLA_U64)
EM_A_PS_POWER (NLA_U64)
EM_A_PS_COST (NLA_U64)
EM_A_PS_FLAGS (NLA_U64)
where EM_A_PD_TABLE_PS can be repeated as many times as there are
performance states (struct em_perf_state).
