spi: imx: Update device tree binding documentation
Update documentation for gpio-cs and num-cs to reflect the standard SPI bindings. The dma properties are optional. Include a warning that native CS do not work in a commonly useful manner with this hardware/driver, and therefor most users probably should use GPIO based CS lines rather than native.
