Added support for SPI slave configurations to the pios SPI layer. Converted the board specific configuration for the PIOS SPI layer to use const static initializers rather than #defines (see pios_board.c). SPI interface between the OP board and the AHRS is now operational at a basic level, capable of moving simple single byte messages between boards. Multi-byte, CRC protected messages will be added on top of this. git-svn-id: svn://svn.openpilot.org/OpenPilot/trunk@759 ebee16cc-31ac-478f-84a7-5cbb03baadba
