imx27-eukrea-mbimxsd27-baseboard passes 'spi-cpol' in the ads7846
touchscreen node, which causes the following dt-schema warning:
imx27-eukrea-mbimxsd27-baseboard.dtb: ads7846@0 (ti,ads7846):
Unevaluated properties are not allowed (spi-cpol was unexpected)
Allow spi-cpol so the binding describes the existing configuration
without changing its SPI mode.
