As reported by kernel-doc:
./drivers/gpu/drm/amd/amdgpu/amdgpu_xgmi.c:1: warning: no structured comments found
./drivers/gpu/drm/amd/amdgpu/amdgpu_ras.c:1: warning: no structured comments found
Those files only contain
/**
* DOC:
*/
markups, but they're included twice there: one to parse
such markup, and another one to parse internal functions.
In the case of amdgpu_xgmi.c, as it has just one such
markup, we can simply include the file once, and let it
parse the entire file without passing arguments to kernel-doc.
This should place everything altogether.
For amdgpu_ras.c, however, we need to remove the kernel-doc
with just internal. This should be re-introduced if this
file ever gets new non-DOC markups.

Allow for reading of information like manufacturer, product number
