Liu Yi L a4544c45e1 intel_iommu: Use correct shift for 256 bits qi descriptor 
In chapter 10.4.23 of VT-d spec 3.0, Descriptor Width bit was introduced
in VTD_IQA_REG. Software could set this bit to tell VT-d the QI descriptor
from software would be 256 bits. Accordingly, the VTD_IQH_QH_SHIFT should
be 5 when descriptor size is 256 bits.

This patch adds the DW bit check when deciding the shift used to update
VTD_IQH_REG.
