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.
BUG=chrome-os-partner:59832
