Fix the following dtbs_check error if dma-coherent is used:

Skip last line - it's obvious. What instead you miss here - the
DTS/target which has this warning. I assume that some existing DTS uses
this property?
I will skip that line.
The binding is for an FPGA based Ethernet MAC. I'm working with
an evaluation platform currently. The DTS for the evaluation platform
is mainline, but my derived DTS was not accepted mainline. So there is
no DTS. This is similar for other FPGA based devices.
If this is not coming from mainline, then there is no warning... we are
not interested in warnings in out-of-tree code, because we are not
fixing them.
Ok. So I would rewrite the description that it just allows dma-coherent
and remove the fix/warning stuff. Is that ok?
That would be okay, but please add answer to why you are making this change.
I already prepared it:
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.
Thanks!
