Subject: drm/amdgpu: initial validate the prime BOs into the CPU domain
MIME-Version: 1.0

Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Just set the GTT domain as mandatory, so that the BO is validated into
it on first use. This allows us to setup the sg table later on.
