The RGB 64-bit 16:16:16:16 float pixel format is needed by windows 10
guest VM. This patch is to add this pixel format support to gvt device
model. Without this patch, some Apps, e.g. "DXGIGammaVM.exe", will crash
and make guest screen black.

dmabuf_obj's destruction relys on GEM release operation, which is managed
in i915 driver. And there is a time window between vgpu's destruction and
its dmabuf_objs' destruction. This patch is to free the orphan dmabuf_objs
correctly after the vgpu passes away.
