drm/amdgpu: enable gfxoff quirk on HP 705G4

[ Upstream commit 2c7795e245d993bcba2f716a8c93a5891ef910c9 ]

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.
