It shouldn't even be necessary to set 'bus_num' since the default is 0.

No, define a "struct spi_board_info" array, and then (in your board
startup code) call at91_add_device_spi() and pass the array and number
of entries.
The at91_add_device_spi() handles all the pin-setup,
spi_register_board_info() and platform_device registration for you.

Also enable CONFIG_SPI_SPIDEV ("User mode SPI device driver support")
in the configuration.
