drm/amd/display: Update bounding box states (v2)
[Why] We need to update each p-state in the bounding box [How] Update states when assigning values to clocks v2: squash in patch to set min values (Alex) Signed-off-by: Alvin Lee <alvin.lee2@amd.com> Signed-off-by: Jerry (Fangzhi) Zuo <Jerry.Zuo@amd.com> Reviewed-by: Hersen Wu <hersenxs.wu@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
