Subject: drm/amd/display: allocate fbc buffer in AMDGPU_GEM_DOMAIN_GTT
Git-commit: 0e5916ffb8b1f0158651f5867c150ceea3d06991
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Currently the FBC buffer is allocated in VRAM, since VRAM usage is
dedicatedly for scanouts, by allocating FBC back buffer in GTT
shall help in conserving VRAM for other purposes.
