[PATCH 11/25] dt-bindings: spi: andestech,ae350-spi: make DMA and interrupts optional

[Benoît Monin]

The ATCSPI200 controller can be used in PIO mode, without DMA, and PIO
transfers can optionally use the controller's interrupt. Make dmas,
dma-names and interrupts optional, and require dma-names if dmas is
specified.
