[PATCH 62/74] drm/amd/display: Update DCN42B stutter latency to match DCN42

[Wayne Lin <Wayne.Lin@amd.com>]

From: Allen Pan <Allen.Pan@amd.com>

[Why]
The DCN42B stutter latencies do not match DCN42, which can lead to
underflow and stutter issues.

[How]
Update the DCN42B LPDDR5/LPCAMM2 stutter latencies to the same
values DCN42 already uses.
