Subject: drm/amd/amdgpu: add raven1 part to the gfxoff quirk list
Git-commit: 975f543e7522e17b8a4bf34d7daeac44819aee5a
Patch-mainline: v5.7-rc6
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
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.
