drm/amd/display: Ensure vmin and vmax adjust for DCE

commit 2820433be2a33beb44b13b367e155cf221f29610 upstream.

[Why & How]
In the commit 32953485c558 ("drm/amd/display: Do not update DRR while
BW optimizations pending"), a modification was added to avoid adjusting
DRR if optimized bandwidth is set. This change was only intended for
DCN, but one part of the patch changed the code path for DCE devices and
caused regressions to the kms_vrr test. To address this problem, this
commit adds a modification in which dc_stream_adjust_vmin_vmax will be
fully executed in DCE devices.
