device: Add a new "SPI" device type

Add support for a new "SPI" device type in the devicetree to bind a
    device on the SPI bus. Allow device to provide chip select number for
    the device as a parameter.

Add spi_bus_operations with operation dev_to_bus which allows SoCs to
    define a translation method for converting "struct device" into a unique
    SPI bus number.
