    GCEA/MMHUB EA error should not result to DF freeze, this is
    fixed in next generation, but for some reasons the GCEA/MMHUB
    EA error will result to DF freeze in previous generation,
    diver should avoid to indicate GCEA/MMHUB EA error as hw fatal
    error in kernel message by read GCEA/MMHUB err status registers.
    
    Changed from V1:
        make query_ras_error_status function more general
        make read mmhub er status register more friendly
    
    Changed from V2:
        move ras error status query function into do_recovery workqueue
    
    Changed from V3:
        remove useless code from V2, print GCEA error status
        instance number
