[PATCH 2/2] Reapply "Revert drm/amd/display: Enable Freesync Video Mode by default"

[Alex Deucher <alexander.deucher@amd.com>]

This reverts commit 11b92df8a2f7f4605ccc764ce6ae4a72760674df.

This conflicts with how compositors want to handle VRR.  Now
that compositors actually handle VRR, we probably don't need
freesync video.

Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/2985
