Add `allwinner,sun60i-a733-dma` to the list of compatible strings for the `sun50i-a64-dma` dtbinding documentation. While the A733 DMA controller shares many similarities with the sun50i-a64 DMA controller, it requires a specific configuration due to differences in: - Interrupt register layout and mapping. - Number of channels per interrupt register. - Support for higher (32G) address widths in LLI parameters.
