hv: More changes to enable GPU passthru

Browse Source 
Snoop control is not supported in the graphics VT-d engine and so should
be disabled in the PTEs. Also enabled iommu for graphics in the
dmar_drhd array.

v2: removed disable iommu in handle_one_drhd and combined if cond.
v3: minor code review changes
v4: moved the snoop control change to ept.c to accomodate upstream changes
