drm/amd/display: Fix urgent latency override for DCN32/DCN321
[Why]
The urgent latency override is useful when debugging issues
relating to underflow.
Current overridden variable is not correct and has no effect
on DCN3.2 and DCN3.21 DML calculations.
[How]
For DCN3.2 and DCN3.21, override the correct urgent latency
variable when bounding box override is present.
