SMU add a new variable mca_ceumc_addr to record
umc correctable error address in EccInfo table,
driver side add EccInfo_V2_t to support this feature
Changed from V1:
remove ecc_table_v2 and unnecessary table id, define union struct
include
EccInfo_t and EccInfo_V2_t.
Changed from V2:
sync patch verion
