Return to avoidance of FIFO overflows



- See comments regarding macro 'RX_FIFO_THR_WA' in file 'spirit1-config.h'

- Reset SPI frequency at 1MHz

- Prepare for performing FIFO handling in IRQ handler

- Disable FIFO overflows by defining macro 'RX_FIFO_THR_WA'

- 'MAX_PACKET_LEN' is 'SPIRIT_MAX_FIFO_LEN-1' (i.e. 95) again
