drm/amd/display: Update minimum stutter residency for DCN314 Z8

Browse Source 
[ Upstream commit 0215ce9057edf69aff9c1a32f4254e1ec297db31 ]

[Why]
Block periods that are too short as they have the potential to
currently cause hangs in other firmware components on the system.

[How]
Update the threshold, mostly targeting a block of 4k and downscaling.
