Subject: drm/amdkfd: Add dGPU support to the MQD manager
Git-commit: ee04955af6b851a4f133d2472bc65c5d8b9aa692
Patch-mainline: v4.20 or v4.20-rc7 (next release)
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

On dGPUs don't set ATC addressing bits and use MTYPE_UC for coherent
memory.
