drm/amd/display: dc_hw_sequencer.c: remove kernel-doc comments

Change comments from kernel-doc style "/**" to normal C comments
"/*" since the comments are not in kernel-doc format.
This fixes around 39 kernel-doc warnings like this one:

drivers/gpu/drm/amd/display/dc/core/dc_hw_sequencer.c:1322: warning:
This comment starts with '/**', but isn't a kernel-doc comment.
Refer Documentation/doc-guide/kernel-doc.rst
