Allow AXI DMA client to configure / report coalesce parameters. Client can
fine-tune irq coalescing parameters based on the transfer load.

AXI ethernet driver uses AXI DMA dmaengine driver. Corresponding changes
for AXI ethernet driver to allow irq coalescing configuration / reporting
via ethtool will be sent to net-next with following subject:
"net: xilinx: axienet: Configure and report coalesce parameters in
DMAengine flow"

  dmaengine: Add support to configure and read IRQ coalescing parameters
  dmaengine: xilinx_dma: Add support to configure/report coalesce
    parameters from/to client using AXI DMA
