Subject: [PATCH] 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.
