iommu/vt-d: Set intel_iommu_gfx_mapped correctly
[ Upstream commit cf1ec4539a50bdfe688caad4615ca47646884316 ]
The intel_iommu_gfx_mapped flag is exported by the Intel
IOMMU driver to indicate whether an IOMMU is used for the
graphic device. In a virtualized IOMMU environment (e.g.
QEMU), an include-all IOMMU is used for graphic device.
This flag is found to be clear even the IOMMU is used.
