dmaengine: idxd: Add descriptor definitions for DIX generate operation

Browse source

The Data Integrity Extension (DIX) generate operation (0x17) computes
the Data Integrity Field (DIF) on the source data and writes only the
computed DIF for each source block to the PI destination address.

Add descriptor definitions for this operation so that user can use
DSA to accelerate DIX generate operation.
