      drm/amdgpu: update athub interrupt harvesting handle · ba54e13f

      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
