The AXI DMA multichannel support is deprecated in the IP and it is no
longer actively supported. For multichannel support, refer to the AXI
multichannel direct memory access IP product guide(PG228). So it is
decided to remove it's complete support from the driver. Inline with
it remove axidma multichannel optional properties i.e xlnx,mcdma and
dma-channels from the binding description. Just to highlight that this
patch intentionally breaks backward compatibility.

- xlnx,include-sg: Tells configured for Scatter-mode in
the hardware.
Optional properties for AXI DMA:
-- xlnx,mcdma: Tells whether configured for multi-channel mode in the hardware.
- xlnx,sg-length-width: Should be set to the width of buffer length register as
configured in hardware. If this property is missing or has invalid width
i.e not in range of 8-26, maximum buffer length width (common to all IP
enabled/disabled in hardware.
- xlnx,enable-vert-flip: Tells vertical flip is
enabled/disabled in hardware(S2MM path).
-Optional child node properties for AXI DMA:
