Add DeviceTree schema for NVIDIA'S SPIDEV controller.
The schema supports both master and slave modes for data transfer
purposes. Specifies required properties: "compatible", "reg", and
"spi-max-frequency".

All the issues with having spidev nodes directly in the DT also apply if
you add a prefix onto it.  Whatever is attached to the SPI controller
needs to be described, not just a placeholder like this.
