Yicong Yang 3d69461807 iommu/arm-smmu-v3: Make default domain type of HiSilicon PTT device to identity
[ Upstream commit 24b6c7798a0122012ca848ea0d25e973334266b0 ]

The DMA operations of HiSilicon PTT device can only work properly with
identical mappings. So add a quirk for the device to force the domain
as passthrough.
