drm/amd/amdgpu: add raven1 part to the gfxoff quirk list

commit 975f543e7522e17b8a4bf34d7daeac44819aee5a upstream.

On my raven1 system (rev c6) with VBIOS 113-RAVEN-114 GFXOFF is
not stable (resulting in large block tiling noise in some applications).

Disabling GFXOFF via the quirk list fixes the problems for me.
