Improve the bindings and make them more usable:
- Pick in spi-cpha and spi-cpol from the SPI node parent, this will specify that we are "type 3" in the device tree rather than hardcoding it in the operating system.
- Drop the u32 ref from the SPI frequency: comes in from the SPI host bindings.
- Make spi-cpha, spi-cpol and port compulsory.
- Update the example with a real-world SPI controller, spi-gpio.
