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

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