[PATCH V2 23/47] drm/amd/display: Fix urgent latency override for DCN32/DCN321

[Wayne Lin]

From: George Shen <george.s...@amd.com>

[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.
