Subject: [PATCH net-next v4 1/6] dt-bindings: net: tsnep: Allow dma-coherent

Within SoCs like ZynqMP, FPGA logic can be connected to different kinds
of AXI master ports. Also cache coherent AXI master ports are available.
The property "dma-coherent" is used to signal that DMA is cache
coherent.

Add "dma-coherent" property to allow the configuration of cache coherent
DMA.
