Subject: [PATCH AUTOSEL 5.7 46/54] drm/amdgpu: disable gfxoff for navy_flounder

From: Jiansong Chen <Jiansong.Chen@....com>

[ Upstream commit 9c9b17a7d19a8e21db2e378784fff1128b46c9d3 ]

gfxoff is temporarily disabled for navy_flounder,
since at present the feature has broken some basic
amdgpu test.
