[PATCH 2/3] drm/amd/display: Enable new commit sequence only for DCN32x

[Rodrigo Siqueira]

Change commit sequence might impact multiple ASICs; for this reason, it
is better to run it only on DCN32x for the first set of validation.
After we get more confident about this change, we should expand it to
all ASICs.
