[PATCH v7 14/14] drm/i915: Enable platform support for vGPU huge gtt pages

[changbin.du at intel.com]

From: Changbin Du <changbin.du at intel.com>

Now GVTg supports shadowing both 2M/64K huge gtt pages. So let's turn on
the cap info bit VGT_CAPS_HUGE_GTT.

v2: Split changes in i915 side into a separated patch.
