drm/amdgpu: Modify nbio block to fit for the unified ras block data and ops

1.Modify nbio block to fit for the unified ras block data and ops.
2.Change amdgpu_nbio_ras_funcs to amdgpu_nbio_ras, and the corresponding variable name remove _funcs suffix.
3.Remove the const flag of mmhub ras variable so that nbio 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 nbio ras block into amdgpu device ras block link list.
5.Remove the redundant code about nbio in amdgpu_ras.c after using the unified ras block.
