Subject: drm/i915/gvt: Enable gtt initialization for BXT.
Git-commit: 665004b8f50612d1e354eb9abd6d97e6eb85a619
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Initialize BXT gtt as SKL/KBL.

v2: All supported platforms share the same gtt ops.
    Remove the platform check by now and let is_supported_device()
    be the gate keeper.
