Update the DMA-350 DT binding to match the current driver behavior.
Allow both:
- "arm,dma-350" as the generic compatible, and
- "cix,sky1-dma-350", "arm,dma-350" for SoC-specific fallback usage.
Also document interrupt topology variants supported by hardware
integration:
- one combined interrupt for all channels, or
- one interrupt per channel (up to 8 channels).

There is no space here. Read the docs, I quite insisted on this last
time. If you make mistakes in this, I doubt you read the docs thus I
doubt you followed the requirements - have actual rights to send it for
example.
I might not need to add the "cix,sky1-dma-350" and can directly use "arm,dma-350" instead. I will rework the code and description accordingly.

What is the point of explaining it? What is the difference between
generic integration and non-generic?
