[PATCH 3/3] exports: Fix export of SPI access functions

[Paul Barker]

* With CONFIG_DM_SPI defined, spi_get_bus_and_cs needs to be used
instead of spi_setup_slave to configure a SPI bus. As spi_setup_slave is
already present in the export list it is reasonable to also export
spi_get_bus_and_cs.

* For the functions listed in the jump table to be callable they must
also be defined in the "exports.h" header. Define the various exported
SPI functions so that they can be used.
