spi: davinci: remove unnecessary call to davinci_spi_setup_transfer()

Remove unnecessary call to davinci_spi_setup_transfer() at the end
of davinci_spi_setup().

davinci_spi_setup_transfer() is registered as the setup_transfer
callback for the bitbang layer and is called independently by
the bitbang layer to setup the transfer before it begins.
