net/mlx5e: add op for getting netdev DMA device
For zero-copy (devmem, io_uring), the netdev DMA device used
is the parent device of the net device. However that is not
always accurate for mlx5 devices:
- SFs: The parent device is an auxdev.
- Multi-PF netdevs: The DMA device should be determined by
the queue.
This change implements the DMA device queue API that returns the DMA
device appropriately for all cases.
