drm/amdgpu: add ras_err_info to identify RAS error source

introduced "ras_err_info" to better identify a RAS ERROR source.

NOTE:
For legacy chips, keep the original RAS error print format.

v1:
RAS errors may come from different dies during a RAS error query,
therefore, need a new data structure to identify the source of RAS ERROR.

v2:
- use new data structure 'amdgpu_smuio_mcm_config_info' instead of
  ras_err_id (in v1 patch)
- refine ras error dump function name
- refine ras error dump log format
