[Why & How]
In the commit 68d1085eb2 ("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.
Fixes: 68d1085eb2 ("drm/amd/display: Do not update DRR while BW optimizations
pending")
