Bug description:
  [Impact]
  After suspend then restart, the System would hang during shutdown.

  [Fix]
  The commit has pushed to upstream but still wait for the maintainer of IOMMU 
to apply.
  
https://lore.kernel.org/linux-iommu/20200721001713.24282-1-baolu...@linux.intel.com/

  Skip the TE disabling for the quirky gfx dedicated iommu and
  the system would not hang during shutdown.

  [test]
  With the patch, the machine restart successfully.

  [Regression Potential]
  low, the patch just skip the TE disabling and wouldn't affect the normal 
usage.
