drm/amd/display: Allow DCN301 to clear update flags
commit 2d418e4fd9f1eca7dfce80de86dd702d36a06a25 upstream.
[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)
