SPI Mode setting was very broken. MSB and LSB sets did not work (MSB is the only one supported) and if LSB was set (which was the default) the ioct to set clock phase would fail. This deprecates all the individual functions, the LSB/MSB functions, and adds an SPI mode selection function. This is usually more understandable, and shows up in a lot more documentation
