dmaengine: idxd: Add descriptor definitions for translation fetch operation
The translation fetch operation (0x0A) fetches address translations for the
address range specified in the descriptor by issuing address translation
(ATS) requests to the IOMMU.
Add descriptor definitions for the operation so that user can use DSA
to accelerate translation fetch.
