AXI ethernet driver uses AXI DMA dmaengine driver. Add support to
configure / report coalesce parameters dynamically during runtime
via ethtool. Add support in DMAengine driver to communicate coalesce
parameters between client and DMA driver. Add support for Tx and Rx
adaptive irq coalescing with DIM in AXI ethernet driver.

Changes in V2:
- Add DIM in AXI ethernet driver.
- Fix following LKP warning in V1:

- Consolidate separate Dmaengine and netdev series in V1.
