[PATCH 24/35] drm/amd/display: Update min Z8 residency time to 2100 for DCN314

[Hamza Mahfooz]

From: Nicholas Kazlauskas <nicholas.kazlauskas at amd.com>

[Why]
Some panels with residency period of 2054 exhibit flickering with
Z8 at the end of the frame.

[How]
As a workaround, increase the limit to block these panels.
