[PATCH 64/81] drm/amd/display: Get freesync properties

[sunpeng.li at amd.com]

From: Harry Wentland <harry.wentland at amd.com>

Eventually we should create proper atomic properties for freesync
but currently freesync is broken and we still have the legacy
properties. Simply return the legacy properties.
