spi: slow down OP <-> AHRS spi link

Browse Source 
Issues have been reported with CRC errors
on the SPI link between the OP and AHRS
boards.  Slowing the link down eliminates
the errors in my testing.

If we speed this link back up in the future,
further investigation will be required to
diagnose the source of the CRC errors.
