dm: spi: Add a uclass for SPI
Add a uclass which provides access to SPI buses and includes operations required by SPI. For a time driver model will need to co-exist with the legacy SPI interface so some parts of the header file are changed depending on which is in use. The exports are adjusted also since some functions are not available with driver model. Boards must define CONFIG_DM_SPI to use driver model for SPI.
