drm/amd/display: more liberal vmin/vmax update for freesync
[Why]
FAMS2 expects vmin/vmax to be updated in the case when freesync is
off, but supported. But we only update it when freesync is enabled.
[How]
Change the vsync handler such that dc_stream_adjust_vmin_vmax() its called
irrespective of whether freesync is enabled. If freesync is supported,
then there is no harm in updating vmin/vmax registers.
