[PATCH V2] drm/amd/pm: disable the SMU13 OD feature support temporarily

The existing OD interface cannot support the growing demand for more
OD features. We are in the transition to a new OD mechanism. So,
disable the SMU13 OD feature support temporarily. And this should be
reverted when the new OD mechanism online.
