  Some boards use SJA1105 Ethernet Switch with SPI CPOL, so document this
to fix dtbs_check warnings:

  arch/arm64/boot/dts/freescale/fsl-lx2160a-bluebox3.dtb: ethernet-switch@0: Unevaluated properties are not allowed ('spi-cpol' was unexpected)

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

Full log is available here: https://patchwork.ozlabs.org/patch/

I'll add cpha, but fsl,spi-cs-sck-delay are coming from unconverted
schema - spi-fsl-dspi.txt.
