The SPI version of Prism54 was sold under a couple of different names and supported by the Linux p54spi driver, but there was never a DT binding for it. Document the four known names of this device and the properties that are sufficient for its use on the Nokia N8x0 tablet. As I don't have this hardware or documentation for it, this is purely based on existing usage in the driver.
