Add dmas and dma-names properties because dspi support dma transfer.
Fix below warnings:
arch/arm64/boot/dts/freescale/fsl-ls1028a-kontron-sl28-var1.dtb: spi@2120000: Unevaluated properties are not allowed ('dma-names', 'dmas', 'little-endian' were unexpected)
        from schema $id: http://devicetree.org/schemas/spi/fsl,dspi.yaml#
