PM: EM: Implement em_nl_get_pds_doit()
When a userspace requests EM_CMD_GET_PDS, the kernel responds with
information on all performance domains. The message format of the
response is as follows:
EM_A_PDS_PD (NLA_NESTED)*
EM_A_PD_PD_ID (NLA_U32)
EM_A_PD_FLAGS (NLA_U64)
EM_A_PD_CPUS (NLA_STRING)
where EM_A_PDS_PD can be repeated as many times as there are performance
domains, and EM_A_PD_CPUS is a hexadecimal string representing a CPU
bitmask.
