Add support of the IOMMU_DEVICE flag.
This flag is used for specifying access to device memory. SMMU would apply
device memory attributes for a DMA transaction. This is required for setting
access to GIC registers, for generating message interrupts. This would ensure that
transactions targetting device memory are not gathered or reordered.
