[PATCH 06/23] drm/amd/display: Enable DML2 override_det_buffer_size_kbytes

[Alex Hung]

From: Yihan Zhu <Yihan.Zhu at amd.com>

[WHY]
Corrupted screen will be observed when 4k144 DP/HDMI display and
4k144 eDP are connected, changing eDP refresh rate from 60Hz to 144Hz.

[HOW]
override_det_buffer_size_kbytes should be true for DCN35/DCN351.
