1.Modify mmhub block to fit for the unified ras block data and ops.
2.Change amdgpu_mmhub_ras_funcs to amdgpu_mmhub_ras, and the corresponding variable name remove _funcs suffix.
3.Remove the const flag of mmhub ras variable so that mmhub ras block can be able to be inserted into amdgpu device ras block link list.
4.Invoke amdgpu_ras_register_ras_block function to register mmhub ras block into amdgpu device ras block link list. 5.Remove the redundant code about mmhub in amdgpu_ras.c after using the unified ras block.
5.Remove the redundant code about mmhub in amdgpu_ras.c after using the unified ras block.
6.Fill unified ras block .name .block .ras_late_init and .ras_fini for all of mmhub versions. If .ras_late_init and .ras_fini had been defined by the selected mmhub version, the defined functions will take effect; if not defined, default fill them with amdgpu_mmhub_ras_late_init and amdgpu_mmhub_ras_fini.

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
