Amdgpu driver is used in an extensive range of devices, and each ASIC has some specific configuration. As a result of this variety, sometimes it is hard to identify the correct block that might cause the issue. This commit expands the amdgpu kernel-doc to alleviate this issue by introducing one ASIC table that describes dGPU and another one that shares the APU info.
