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
