This patch introduces support for allocating and deallocating the DMAH object. Further details: ---------------- The DMAH API is exposed to upper layers only if the underlying device supports TPH. It uses the mlx5_core steering tag (ST) APIs to get a steering tag index based on the provided input. The obtained index is stored in the device-specific mlx5_dmah structure for future use. Upcoming patches in the series will integrate the allocated DMAH into the memory region (MR) registration process.
