Split the common code from sc16is7xx driver and move the I2C and SPI bus
parts into interface-specific source files.
sc16is7xx becomes the core functions which can support multiple bus
interfaces like I2C and SPI.
No functional changes intended.
Also simplify and improve Kconfig entries.
- Capitalize SPI keyword for consistency
- Display list of supported ICs each on a separate line (and aligned) to
facilitate locating a specific IC model
- Add Manufacturer name at start of description string
- Add UART keyword to description string
