drm/amd/display: Move DIO documentation to the right place
When building the kernel-doc, it complains with the below warning: ./drivers/gpu/drm/amd/display/dc/link/hwss/link_hwss_dio.h:1: warning: no structured comments found ./drivers/gpu/drm/amd/display/dc/link/hwss/link_hwss_dio.h:1: warning: no structured comments found This warning was caused by the wrong use of the ':export:' and the lack of function documentation in the file pointed under the ':internal:'. This commit addresses those issues by relocating the overview documentation to the correct C file, removing the ':export:' options, and adding two simple kernel-doc to ensure that ':internal:' does not have any warning.
