Subject: drm/amdgpu: Modify mca block to fit for the unified ras block data
and ops
Git-commit: b0e2062dc8978869c1dd96d92027f74b361d5eb7
Patch-mainline: v5.18-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
1.Modify mca block to fit for the unified ras block data and ops.
2.Define special .ras_block_match function for mca block to identify itself.
3.Change amdgpu_mca_ras_funcs to amdgpu_mca_ras_block(amdgpu_mca_ras had been used), and the corresponding variable name remove _funcs suffix.
4.Remove the const flag of cma ras variable so that cma ras block can be able to be inserted into amdgpu device ras block link list.
5.Invoke amdgpu_ras_register_ras_block function to register cma ras block into amdgpu device ras block link list.
6.Remove the redundant code about cma in amdgpu_ras.c after using the unified ras block.
