Subject: [PATCH] drm/amdgpu: enable gfxoff quirk on HP 705G4

From: Peng Liu <liupeng01@...inos.cn>

Enabling gfxoff quirk results in perfectly usable
graphical user interface on HP 705G4 DM with R5 2400G.

Without the quirk, X server is completely unusable as
every few seconds there is gpu reset due to ring gfx timeout.
