Subject: [-mm patch 3/4] AVR32: Move spi device definitions into main board
 setup file

There's no point in having a separate file just to set up the board-
specific data for spi. By moving it into the rest of the board-
specific setup code, we can also make sure that the data is
registered before we register the spi master controller.

This patch also records the GPIO pin to use as chip select in the
controller_data member of the spi_board_info data for each device.
