i think we can use a function to retrieve this information without storing it separately.
likes: ret = smu_get_atom_data_table(smu, index, &size, &frev, &crev,
(uint8_t **)&header);
because these information is a generic information from atom_common_table_header.
and other function don't care it except in smu_v11_0_get_clk_info_from_vbios.
