Subject: [PATCH] drm/xe: Do not mark 1809175790 as a WA
Additional programming annotated with Wa_<number> should be reserved to
those that have a official workaround. Just pointing to a bug or
additional reference can be done with something else. Copy what i915
does and refer to it as "hsdes: ....".
