spi: dt-bindings: samsung: make dma properties not required
...
Since the addition of the driver in 2009, the driver selects between DMA
and polling mode depending on the transfer length - DMA mode for
transfers bigger than the FIFO depth, polling mode otherwise. All
versions of the IP support polling mode, make the dma properties not
required.

spi: dt-bindings: samsung: Convert to dtschema
...
Convert the Samsung SoC (S3C24xx, S3C64xx, S5Pv210, Exynos) SPI
controller bindings to DT schema format.
The conversion also drops requirement from providing controller-data and
its data for each of SPI peripheral device nodes. The dtschema cannot
express this and the requirement is being relaxed in the driver now.
