      Pmfw read ecc info registers and store values in
      eccinfo_table in the following order
      
      umc0 ch_inst 0, 1, 2 ... 7
      umc1 ch_inst 0, 1, 2 ... 7
      ...
      umc3 ch_inst 0, 1, 2 ... 7
      
      Driver should convert eccinfo_table_idx to channel_index according
      to channel_idx_tbl.
