Commit 81d0bcf99009 ("drm/amdgpu: make display pinning more flexible (v2)")
allowed for newer ASICs to mix GTT and VRAM, this change also noted that
some older boards, such as Stoney and Carrizo do not support this.
It appears that at least one additional ASIC does not support this which
is Raven.
We observed this issue when migrating a device from a 5.4 to 6.6 kernel
and have confirmed that Raven also needs to be excluded from mixing GTT
and VRAM.
