linux: Convert linux SPI code to use the generic spicmds.c code
Use the generic spi send/receive code on Linux. Update the replicape code to use the updated command format. Also, update the replicape code to turn off the stepper motors on a shutdown event. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
