Subject: drm/amdgpu: No need support vcn decode
Git-commit: ad31da434eb3c41fe291851316267fa73d352bed
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
As no need to support vcn decode feature, so disable the
ring for SR-IOV.
