[PATCH 71/87] drm/amd/display: populate last calculated bb state with max clocks

From: Jun Lei <Jun.Lei at amd.com>
[why]
update_bounding_box calculates intermediate bb states based on clock relationship
however, the last state doesn't need to maintain a minimum relationship, but should
actually contain maximum of every clock. otherwise maximum clocks are not usable
[how]
once the calculated bb is built, override the last state with max values
