drm/amd/display: Allow DCN301 to clear update flags
[Why & How]
Not letting DCN301 to clear after surface/stream update results
in artifacts when switching between active overlay planes. The issue
is known and has been solved initially. See below:
(https://gitlab.freedesktop.org/drm/amd/-/issues/3441)
Fixes: f354556e29f4 ("drm/amd/display: limit clear_update_flags t dcn32 and above")
